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 transmitter performs the parallel-to-serial conversion and generates the internal high-speed clock for the serial output. The receiver performs serial-toparallel conversion, recovers the clock and data from the serial input, and detects the K28.5 character (Fibre Channel standard "SYNC" transmission character).
