TriQuint’s Fibre Channel transmitter (TQ9501) and receiver (TQ9502) are

part of the FC531/FC1063 (Fibre Channel 531 and 1063 Megabaud) chip

set. In addition to the transmitter and receiver, TriQuint offers the ENcoder/

DECoder (TQ9303 ENDEC). The TQ9501, TQ9502, TQ9303 and a gigabit

fiber optic module set provide a complete solution for Fibre Channel's FC0

and FC1 layers as well as partial support for the FC2 layer.

The TQ9501 and TQ9502 are designed in TriQuint's proprietary 0.7-micron

GaAs process, enabling the transmitter and receiver to run at higher speeds

and lower power than with conventional processes. The transmitter and

receiver data interface has been selected to be 10 bits in order to conserve

input/output power and to reduce pin count and package size. The trans-

mitter performs the parallel-to-serial conversion and generates the internal

high-speed clock for the serial output. The receiver performs serial-to-

parallel conversion, recovers the clock and data from the serial input, and

detects the K28.5 character (Fibre Channel standard “SYNC” transmission

character).

The TQ9303 ENDEC implements 8b/10b encoding and decoding, ordered

set encoding and decoding, parity checking and generation, 32-bit CRC

checking and generation, and word synchronization as defined in the

Fibre Channel Physical and Signaling Interface Standard (FC-PH).

Fibre Channel provides a high-speed physical layer for Intelligent

Peripheral Interface (IPI) and Small Computer System Interface (SCSI)

upper-layer command sets, High-Performance Parallel Interface (HIPPI)

data link layer, and other user-defined command sets. Fibre Channel

replaces the SCSI, IPI and HIPPI physical interfaces with a higher-

speed interface capable of driving longer distances.
