Features
General Description
The VSC7146 is a 2.5Gb/s Transceiver optimized for ease-of-use and efficiency in high-performance data
transmission systems. The VSC7146 accepts two 10-bit 8b/10b encoded transmit characters, latches them on
the rising edge of Transmit Byte Clock (TBC) and serializes the data onto the TX+/- differential outputs at a
baud rate, which is 20 times the TBC frequency. The VSC7146 also samples serial receive data on the RX+/-
differential inputs, recovers the clock and data, deserializes it onto two 10-bit receive characters, outputs a
recovered clocks at one-twentieth o
f the incoming baud rate and detects Fibre Channel “comma” characters.
The VSC7146 contains on-chip Phase-Lock Loop (PLL) circuitry for synthesis of the baud-rate transmit clock,
and extraction of the clock from the received serial stream. These circuits are fully monolithic and require no
external components.
