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
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.

Fibre Channel is optimized for predictable transfers of
large blocks of data, such as those used in file
transfers between processors (super computer,
mainframe, super-mini, etc.), storage systems (disk
and tape), and output-only devices such as laser
printers and raster scan graphics terminals.
TriQuint offers two chip sets for Fibre Channel: the
TQ9501 and TQ9502 chip set for 531.125 Mbaud and
1.0625 Gbaud, and the GA9101 and GA9102 chip set
for the 265.625 Mbaud rate.
Functional Description – TQ9501 Transmitter
The Fibre Channel protocol is implemented in
hardware, making it simple, efficient and robust. The
lower-level physical interface is decoupled from the
higher-level protocol allowing the Fibre Channel to be
configured with various topologies, including point-to-
point, multi-drop bus, ring, and cross point switch.
Fibre Channel supports distances up to 10 Km at baud
rates of 132.8125 Mbaud to 1.0625 Gbaud. Copper
media such as Coax and STP (Shielded Twisted Pair)
are used for shorter distances while fiber optic cables
are used for longer distances.
Applications for the TQ9501 and TQ9502 include serial
SCSI, IPI, HIPPI, point-to-point serial communication,
ATM and other networking applications.
Figure 1. TQ9501 Transmitter
The TQ9501 serializes a 10-bit TTL input into a
differential PECL output. The TQ9501 is composed of
an input register, a parallel-to-serial converter, a PLL
clock generator, a differential output buffer and a PECL-
to-TTL translator, as illustrated in Figure 1.
The self-contained PLL (Phase-Locked Loop) clock
generator requires no external components. It
generates an internal high-speed bit clock for the serial
output, an internal byte clock for the parallel-to-serial
converter and BYTECLK, based on REFCLK (REFerence
CLocK). BYTECLK is used by the TQ9303 ENDEC to
TXD0..9 are latched into the input register on the rising
edge of TXCLK. The parallel-to-serial converter
serializes the data into a differential PECL buffer. TXD9
is sent first and TXD0 is sent last.
