PMC-HSSERIAL2 is a single-wide PCI Mezzanine Card (PMC) that provides
four high-speed asynchronous or synchronous serial channels for space-constrained,
high performance commercial and military data communications applications requiring
high speed serial with minimal CPU overhead. The card supports 33/66 MHz PCI
operation and 3.3V or 5.0V PCI bus signaling.
A maximum data rate of 10 Mb/s is supported for synchronous protocols using an
external clock. Up to 2 Mb/s is supported for asynchronous protocols, with popular baud
rates of up to 921.6 Kbaud available using the standard 14.7456 MHz oscillator in RS422 interface mode. Each of the four channels is fully programmable to support many
high-performance serial communications protocols, such as synchronous, monosync,
bisync, HDLC, SDLC, LAPB, LAPD, ISDN, and PPP.
PMC-HSSERIAL2 supports a wide selection of physical interfaces, configurable by
software alone. Channels can be individually selected as RS-232, RS-422, EIA-449, EIA530, or V.35. No hardware re-configuration is required. Seven signal pairs for each
channel are available at the rear-panel P4 connector and the front-panel I/O connector.
An optional transition cable is available to interface the 68-pin front-panel I/O connector
to four DB25s.
A 14.7456 MHz standard oscillator provides standard asynchronous baud rates. Also, a
user-supplied oscillator location is available for custom baud rate generation. Interrupts
are fully supported for each channel. Interrupt sources include transmission error,
reception error, completions of transmit packets and completions of receive packets.
The card has a central receive FIFO and a central transmit FIFO, each 128 deep by 32
bits wide. Additionally, each channel has a local receive FIFO 17 deep by 32 bits wide,
and a local transmit FIFO of 8 deep by 32 bits wide. Eight DMA controllers are available
to enable the central FIFO to burst into shared memory. PMC-HSSERIAL2 must be
plugged into a CPU slot that has bus mastering capability.
The PMC uses a high-performance Siemens PEB20534 Serial Communication Controller
with integral PCI bus interface. The chip is hosted by the system via Intel’s 21154
transparent PCI-to-PCI bridge chip.
