VSC7125QU中文资料1.0625 Gbits/sec Fibre Channel Transceiver数据手册Microchip规格书

描述 Description

General Description
The VSC7125 is a full-speed Fibre Channel Transceiver optimized for Disk Drive and other space constrained applications. 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 VSC7125 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 Fibre Channel “Comma” characters. The VSC7125 contains on-chip 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.
