Functions
The LV25300M is a tuning system that supports the LC75030W (SANYO audio DSP) that allows the creation of standard
tuner modules. Various setting changes can be performed with the software of the control microcontroller according to the
intended application, making the LV25300M ideal for combined use with the LC75030W. Small tuner modules can be
developed with a smaller number of parts compared to conventional tuners and at a lower total cost. Since the LV25300M
has a serial bus (CCB SANYO bus), the number of communication lines with the microcontroller is reduced by 4 and line
routing problems during set production can be avoided, making a smaller board size possible. AM/FM wave demodulation
is done through digital processing by outputting the IF signal (450 kHz) of the LV25300M to the LC75030W.
Since the LC75030W has a function to change the IF selectivity according to the level of adjacent interference, just two
10.7 MHz ceramic filters suffice to achieve both high sound quality and adjacent interference, which used to be difficult until
now because these are somewhat mutually exclusive characteristics. Moreover, the LV25300M comes with an antenna
switching diversity function that switches two antennas in response to various electric field changes during operation, a
malfunction prevention circuit that operates through antenna switching frequency detection, and a weak electric field
detection and antenna fixing circuit that uses S meter voltage, making stable reception possible.
Optimum tuner reception is possible by outputting the voltages of the LV25300M' S meter output and the AM/FM IF outputs
to a DSP and judging the radio wave status in real time, and performance combinations and specification differentiation can
be performed by software.

consultation with a SANYO representative
prior to the use of the device.
Overview
The LC78648NEH integrates, on a single chip, the RF signal processing, servo control, EFM signal processing,
and audio signal processing required for audio CD playback.
This single IC can perform all the CD data signal processing required to convert the signal read from the disc to
an analog audio signal. A basic CD player system can be implemented with just three ICs
(this IC, a microcontroller, and a driver IC) and a minimal number of external components.
The LC78684E integrates, on a single chip, CD-ROM signal-processing functions, MP3 signal-processing
functions, and CD-DA anti-skip signal-processing functions.
These signal-processing functions are implemented as hard-wired circuits for reduced power consumption.
The LC78684E, in combination with a CD DSP, DRAM, an audio D/A converter, and other devices can
implement CD players that provide playback of MPEG layer 3 (MP3) audio recorded on CD media as well as
anti-skip CD-DA playback.

The LC78685V is a WMA decoder IC. This IC is implemented using a dedicated hard wired circuit structure
to achieve low power consumption. Various format (CD-DA, MP3, and WMA) audio data recorded on CDs can
be played back by adding this IC to a system structure consisting of a CD player signal-processing IC and a
CD-MP3 IC (such as the LC78684).
The LC78685V makes it easy to implement CD players that provide multiformat decoding functions.
Features

Overview
Overview
The LA17000M is a car audio system tuner IC that integrates both a PLL frequency synthesizer and all AM/FM
functions on a single chip. The LA17000M combines the functions of two ICs, a PLL IC (such as the LC72144)
and an FM tuner IC (such as the LA1781M) on a single chip that provides PLL, AM (upconversion), FM FE, FM IF,
NC, MCP, and MRC functions. The LA17000M achieves increased performance, adjustment-free manufacturing,
and high reliability at low cost in car tuner systems by providing an optimal functional allocation in the IC.

Block Diagram
The LC75410E/W is an electronic volume and tone control IC that implements a rich set of audio control
functions with a minimal number of external components. Functions include volume, balance, fader,
bass/midrange/treble, and loudness controls, as well as input selection/switching functions and an input
gain control.
Functions
■ Volume control: A total of 161 positions from 0 dB to -79.5 dB in 0.5 dB steps and -∞ dB.
A balance function can be implemented by controlling the left and right channel volume controls separately.
■ Fader control: The rear or front outputs can be attenuated by one of 16 levels
(A total of 16 settings with attenuations of 0 to -2 dB in 1dB steps, -2 to -20 dB in 2 dB steps, -20 to -30 dB in 10 dB steps,
and -45, -60, and -∞ dB settings.)
■ Bass/midrange/treble controls: Each band can be controlled in 1 dB steps from 0 dB to ±6 dB, and in 2 dB steps from
±8 dB to ±12 dB
■ Input gain control: The input signal can be amplified by 0 to +18.75 dB in 1.25 dB steps
■ Input switching: One of five input systems (left and right channels) can be selected
(Four of the input systems are single-ended inputs, one uses differential inputs.)
■ Loudness control: The -32 dB position of the 2 dB step volume control ladder resistor can be tapped and a loudness
function implemented with external capacitor and resistor components
Features
■ On-chip buffer amplifiers reduce the number of external components
■ Internal switches are implemented in a silicon gate CMOS process that minimizes the noise generated when switching.
This results in low noise even when switching in the no-signal state.
■ Zero-cross switching circuits used for low noise even when input signals are present
■ Built-in VDD/2 reference voltage generation circuit
■ All functions are controlled using serial data (CCB)
■ Packages: LC75410E: QIP64E (14 14 mm)
LC75410W: SQFP64 (10 10 mm)

Overview
Overview
The LA1776M is a car radio AM/FM tuner IC that is based on the current LA1787M but features improved AM
upconversion (for improved reception characteristics) and improvements in most other characteristics as well.
The LA1776M pin arrangement is only slightly changed from the LA1787M for easy printed circuit board pattern
design.
Functions
The LC72350 Series (LC72358N, LC72362N, and LC72366) are system-on-chip electronic tuning
microcontrollers with a 1.33 µs instruction execution time.
These devices include both a high-speed locking circuit and a high-performance direct PLL circuit that can control
the local oscillator C/N characteristics.
Functions
■ FM IF
■ AM upconversion
■ Noise canceller
■ FM/AM switch
■ MRC
■ ROM: 16 KB (LC72358N)
24 KB (LC72362N)
32 KB (LC72366)
■ RAM: 512 nibbles (LC72358N and LC72362N)
1024 nibbles (LC72366)
■ A/D converter: 6-bit successive approximation A/D converter with 6 input channels
■ PLL: Built-in sub-charge pump for high-speed locking, built-in dead zone control
■ Serial I/O: Three channels (8-bit 3-wire serial I/O)
■ Multiple interrupt support: 4 levels
■ Cycle time: 1.33 µs (4.5 MHz)
■ QTP version: LC72P366
■ Package: QIP80E (14 20 mm)
Features
■ Characteristics improved by new noise prevention measures in the mixer and amplifier blocks
■ Three-signal characteristics improved due to increased dynamic range in the FM front end mixer
■ Improved AM practical sensitivity and saturation signal-to-noise ratio
■ FM S-meter shifter function can adjust for sample-to-sample variations in the S-meter
(Fixed resistors are used for SD, KEYEDAGC, MUTE ON ADJ, MUTE ATT, SNC, and HCC.)
■ High-speed search is possible using the FM band muting time constant switching function
■ The low power consumption of the earlier device has been reduced even further
■ Increased flexibility in the MRC setting
■ Package: QIP64E (14 14 mm)

The LC723780 series are large-memory ETR controllers that provide up to 128 KB of ROM and up to 8 KB of
RAM.
In addition to a rich set of table reference instructions to take advantage of the large ROM capacity, these devices
also feature an improved interrupt system for direct control of the CD mechanism and the CD DSP, support for
RDS products, and powerful communications for use within the end product and with external systems as well.
In car audio applications in particular, these communication functions allow a reduction in the number connecting
wires between the front panel circuit board and the main system circuit board.

The LA4708NF also features a full complement of protection circuits and a standby mode switch.
Note that the LA4708NF is pin compatible with the LA4705NA (car stereo 17 W two-channel power amplifier
IC), and allows end product power to be increased simply by switching ICs.
(Pins 1 and 9 must be left open to allow the same circuit board to be used.)
