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

a10-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 automatic speed negotiation protocols.

Acombined 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.
