PMC-HS-SERIAL is a single-wide PCI Mezzanine Card (PMC) that provides four high-speed
asynchronous or synchronous serial channels
for space-constrained, high-performance
communications applications.
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
14.745 MHz oscillator in RS-422 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-HS-SERIAL supports a wide selection of
physical interfaces, configurable by software
alone. Channels can be individually selected
as RS-232, RS-422, EIA-449, EIA-530, 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 frontpanel I/O connector. An optional transition

cable is available to interface the 68-pin frontpanel I/O connector to four DB25s.
A 14.7456 MHz standard oscillator provides
standard asynchronous baud rates. In addition, 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. The PMC uses a high-performance
Siemens PEB20534 Serial Communication
Controller with integral PCIbus interface.
The PMC-HS-SERIAL addresses a variety of
applications including data communications,
LAN/WAN, networking and telecommunications.
