Dual Speed 10-bit Serializer/Deserializer VSC7145 Storage Communication Products Product Brief Features and Benefits Dual Speed Operation: - Fibre Channel: 1.06/2.12 Gb/s - Gigabit Ethernet: 1.25 Gb/s - InfiniBandTM: 2.5 Gb/s 10-bit, SSTL_2 or SSTL_3 Interface HSPI Interface Compliant ASIC-FriendlyTM Timing to the Transmitter Separate Transmitter/Receiver Rate Controls support Auto Speed Negotiation No Passives needed on High Speed Signals On-chip, 100 Ohm Termination Write Pre-Emphasis in Transmitter Cable Equalization in Receiver Analog/Digital Signal Detection Flexible Reference Clock Single 3.3V Supply, 800mW 64-pin, 14 mm PQFP Package Pin Compatible to Agilent HDMP-263x General Description 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 a 10-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 ...
