Fibre Channel chipsets
The TQ9303 ENDEC (ENcoder/DECoder) implements 8b/10b encoding
and decoding, ordered set encoding and decoding, and parity checking
and generation as defined in the Fibre Channel Physical Signaling
Interface Standard (FC-PH). The ENDEC fully implements the FC-1 layer
of the Fibre Channel Standard. Implemented in a 0.8-micron CMOS
process, the ENDEC also performs 32-bit CRC checking and generation
as defined in the FC-2 layer of the Fibre Channel specification.
• Suitable for proprietary serial
links (virtual ribbon cable)
• Implements 8b/10b encoding
and decoding
• Implements ordered set
encoding and decoding
• Checks and generates 32-bit
CRC and parity
The TQ9303 ENDEC interfaces directly to TriQuint’s FC-0 layer Fibre Channel

Triquint’s Transmitter and Receiver devices are designed with TriQuint’s
proprietary 0.7-micron GaAs process. The Tx and Rx interface directly to
copper-based electrical media or to a fiber-optic module. The Transmitter
performs parallel-to-serial conversion on the encoded data and generates
the internal high-speed clock for the serial output data stream. The Receiver
recovers the clock and data from the input serial stream, performs serial-
to-parallel conversion, and detects and aligns on the K28.5 character.
