General Description
The VSC7145 is a dual-speed Fibre
Channel, Gigabit Ethernet and
InfiniBand Serializer/Deserializer
(SerDes) optimized for performance
and power in an industry-standard
pinout. It accepts 10-bits of SSTL, 8B/
10B encoded transmit data, latches it
synchronously to the Transmit Byte
Clock (TBC) and serializes it onto the
SO differential output at a baud rate
which is 10, 20 or 40 times the
REFCLK frequency. The VSC7145
samples serial receive data on the SI
input, recovers the clock and data,
deserializes it onto a 10-bit SSTL bus
and outputs two recovered clocks at
1/10th or 1/20th of the baud rate. Both
disparities of the K28.5 characters are
detected and used for aligning the
serial data to the parallel output bus.
Independent speed selectors control
the transmitter and receiver separately
to support industry-standard auto-
matic speed negotiation protocols. A
combined analog/digital signal detect
circuit indicates the presence of valid
signal levels on the SI input. The
VSC7145 contains on-chip PLL
circuitry for synthesis of the bit rate
transmit clock, and extraction of the
clock from the received serial stream.
The parallel bus of the VSC7145 is
compliant with the High Speed Parallel
Interface (HSPI) standard developed
by the T11.2 Fibre Channel
Committee.
