We can deliver application-specific solutions for reception, drawing on a complete range
of silicon tuners that cover all the major standards for hybrid terrestrial, cable and satellite
reception. We also support peripheral functions, such as advanced audio and HDMI
interfaces, and provide an extensive portfolio of standard products for TVs.
We use next-generation packaging to save space, lower costs, and improve AV content
security, and we reduce energy consumption with low-power technologies that dramatically
increase efficiency. We design for ruggedness, supplying devices that stand up to intensive
use, and we deliver the high integration needed to simplify development, lower BOM and
production costs, and reduce time-to-market.
We are known for innovation and our ability to introduce new technologies that set the

Smart-card reader interface
Smart-card reader ICs TDA8024 and TDA8034
These are complete, cost-efficient analog interfaces for asynchronous
smart cards. They provide all the supply, protection, and control
functions between a smart card and the microcontroller. The TDA8034
is the same as the TDA8024, but without a DC/DC converter. They are
available with demo kits.
The TDA8024 and TDA8034 are both NDS and EMV 4.2 compliant, and
they both can supply a VCC of 5 V to the smart card. The system supply
voltage influences device selection. Use the TDA8034 when the system
supply voltage is 5 V +/- 3%. This will ensure that the card VCC value is a
minimum of 4.75 V with a current load of 65 mA. In systems that can
only supply a voltage of 5 V +/- 10%, the TDA8024 is a better choice,
because it can guarantee a proper value on VCC = 5 V. The TDA8034 is
available in a 24-pin HVQFN or, to meet low-cost requirements, can be
housed in a 16-pin SO package. The TDA8034 is not pin-compatible
with the TDA8024, which has 28 pins.
 L DO instead of DC/DC means that VDDP should be >4.85 V to
guarantee VCC = 4.75 V min with 65 mA load
 On board oscillator or possibility to use external clock source on

 Shutdown mode on both packages

8.1 8/16/32-bit microcontrollers
8.2 I2C GPIO expanders
We offer highly-integrated and cost-effective microcontrollers,
from the smallest 8-bit to the highest performing 32-bit ARM
solutions.
Our GPIO expanders make it easy to increase the number of I/O using
the I2C-bus. Add inputs for a keypad, a switch, signal monitoring, or fan
control, or add outputs for LED control, an ACPI power switch, a relay,
timers, or sensors.
The LPC111x family, based on Cortex-M0, is an excellent choice for
standby microcontroller tasks. It can be used for power management,
system and human interface monitoring (including remote control and
keypad), signaling, LEDs, and more. The family delivers the outstanding
performance of a 32-bit architecture, with best-in-class power
consumption, and the optimized code footprint enables memory cost
reduction.
The NXP approach lets designers work with a single ARM development
environment to cover all their processing needs, from ARM7 and ARM9
to Cortex-M. Our portfolio also includes an industry-leading selection
of enhanced 80C51.

Combat “feature creep” by increasing the number of I/O ports instead
of adding a new microcontroller. Or, enable seamless migration to
a newer microcontroller and still keep the same peripherals. Using
expanders eliminates costly, congested PCBs, since a trace or wire isn’t
needed for each signal.
NXP offers an extremely wide selection. We have 4-, 8-, 16-, and 40-bit
formats, support quasi-directional and push-pull outputs, and offer
options with interrupts and/or resets — all in a wide range of packages.

8.6 I2C level shifters
These devices provide digital logic level translation between a host
processor and a slave device. This is an important part of voltage level
shifting, since the host processor’s I2C voltage continues to go down
while the voltages used by the peripheral devices remain unchanged.
We offer a very large selection of active and passive level shifters, and
have evolved our NVT20xx family to include widths of 1, 2, 3, 4, 6, 8,
and 10 bits.

iscrete components for the main processing board
9.1 Power solutions
Since integrated circuits typically use a lower core supply voltage
than interfaces and memory devices, most boards require a number
of different supply voltages. Our power solutions include a variety of
devices, including medium-power Schottky diodes, bipolar transistors,
and MOSFETs, to help create efficient, cost-effective linear regulators
and DC/DC converters.
 The PBSS4041PZ can be used as a linear PNP regulator to generate
2.5 and 1.5 V analog supplies. It delivers excellent gain up to 15 A
ICM while supporting 5.7 A of continuous current.
 Supporting 1.2 or 1.8 V, the PMEG2005EH, PMEG4010EH, and
PMEG4030ER are excellent options for the freewheeling Schottky
diodes commonly used in DC/DC conversion.
 The BSP030, a 10 A, N-channel MOSFET in an SOT233 package, can
be used as an external MOSFET for synchronous rectification.
 The TL431xxSDT series of shunt regulators, along with the BC847,
a general-purpose transistor, are recommended for low-power,
discrete linear voltage regulators.

10.1 LED drivers for panel backlight unit
UBA3070 pin configuration (SO8 and DIP8)
Our LED backlight solutions use a power-efficient boundary conduction
mode of operation. This enables use of a smaller inductor value and
avoids reverse recovery losses in the freewheel diode. It also enables
use of a single, loosely controlled input voltage for multiple LED strings.

 Switch-mode buck converter capable of driving LED strings
up to 600 V
 Direct PWM dimming
 Fast transient response through cycle-by-cycle current control

10. Components for the backlight and panel
10.2 Discretes for backlight and panel
Our discretes portfolio covers other functions, too, including power for
LCD source drivers, LCD backplane and digital controls, charge pumps,
and load switches from 1 to 3 A. For example, the Schottky diodes can
be used for buck, boost, and negative/positive charge pumps. The low
VCEsat transistors support high-current load switches and Vcom buffers,
and the medium-power transistors can be used for external, low-power
linear regulators.
Our discretes portfolio increases efficiency in LED backlight units. The
high-voltage, low-voltage, and low VCEsat transistors enable cost-efficient
emitter switches for high-voltage LED drivers and single switches in
low-voltage LED strings. The small-signal MOSFETs are well suited for
use in general-purpose single switches in low-voltage LED strings. The
medium-power Schottky diodes can operate as freewheeling diodes
that offer the lowest forward voltage drops, high power density, and
superior efficiency.

RF communication with remote control unit
To meet the growing demand to replace IR remote control with
low-power, robust RF communication, NXP offers solutions based
on the RF4CE standard protocol.
JN5148 block diagram
The JN5148 is especially well suited for high-end and connected
TV applications, where it can be used as the core of a remote controller.
It has the processing power to include “TV mouse” motion-sensing
algorithms as well as running the RF4CE protocol. It can also be used as
the power-management and wake-up controller of the TV set itself.
In universal remotes, its dual-boot capability can be used to control
consumer appliances running the RF4CE protocol as well as
home-automation systems running ZigBee-HA or -SE protocols.
