VSC8228RCEV-01

VSC8228 Dual Channel Multirate Signal Conditioner and Retimer The VSC8228 is a dual repeater/retimer for Fibre Channel, Gigabit Ethernet, SONET/SDH, and Infiniband applications. The VSC8228 contains dual FibreTimer™ clock recovery units (CRU) for bidirectional signal conditioning in system interconnect and serial backplane applications. The device supports rates from 125 Mbps up to 4.25 Gbps. Using a single reference clock for acquisition, the VSC8228 retransmits the incoming serial data synchronously to the reference clock in retimer mode or to the incoming data in repeater mode. In the retimer mode, add/drop elasticity buffers insert/delete Fibre Channel fill words to account for timing differences in the incoming data and local reference clock. Applications An analog signal detect function is integrated into both channels. In the retimer mode, the device monitors the incoming data for run-length violations and K28.5- symbols. The inputs on both the transmit and receive channels can be looped back to the outputs of the opposite channels for diagnostic purposes. The device provides a built-in pattern generator and checker. An optional half-rate clock for SGMII applications is provided on the receive channel output. • Typical power: 360 mW • Fibre Channel switches, disk arrays, RAID subsystems, host bus adapters • Gigabit Ethernet line cards • Blade server backplanes Specifications • Single 1.2 V and/or 1.8 V supply • 10 mm x 10 mm, 64-pin TQFP package • SPI or two-wire serial interface A high degree of signal integrity is maintained via differential I/O, onchip input and output terminations, input equalization, and output deemphasis. The programmable input equalization circuit compensates for the frequency limitations of long printed circuit board (PCB) traces, backplanes, connectors, and cables. Equalization, de-emphasis, output drive levels, data rate, and other features are configured through industry standard serial interfaces (Two-wire or SPI). The device may be powered from a single 1.2 V supply, single 1.8 V supply, or both a 1.2 V and 1.8 V supply. The 1.8 V supply is required to meet the LVPECL output swing levels. The device has current-mode logic (CML) inputs and outputs that can be AC-coupled for LVPECL and LVDS compatibility. The IC is packaged in a compact 10 mm x 10 mm, 64-pin TQFP package. Typical power dissipation for a 1.2 V supply is 360 mW.
