General Description  
The VSC7126 is a full-speed Fibre Channel Transceiver optimized for Host Adapter and other space- con-  
strained applications. It accepts two 10-bit 8B/10B encoded transmit characters, latches them on the rising edge  
of TBC and serializes the data onto the TX+/- PECL differential outputs at a baud rate which is twenty times the  
TBC frequency. It also samples serial receive data on the RX+/- PECL differential inputs, recovers the clock  
and data, deserializes it onto two 10-bit receive characters, outputs a recovered clocks at one twentieth of the  
incoming baud rate and detects Fibre Channel “Comma” characters. The VSC7126 contains on-chip PLL cir-  
cuitry 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.
