Features
General Description
The VSC7135 is a 1.25Gb/s Ethernet Transceiver optimized for Gigabit Ethernet or 1000Base-X applica-
tions. It accepts 10-bit 8B/10B encoded transmit data, latches it on the rising edge of REFCLK and serializes it
onto the TX PECL differential outputs at a baud rate which is ten times the REFCLK frequency. The VSC7135
also samples serial receive data on the RX PECL differential inputs, recovers the clock and data, deserializes it
onto the 10-bit receive data bus, outputs two recovered clocks at one-twentieth of the incoming baud rate and
detects “Comma” characters. The VSC7135 contains on-chip PLL circuitry for synthesis of the baud-rate trans-
mit clock, and extraction of the clock from the received serial stream. These circuits are fully monolithic and
require no external components.
