The device is designed to perform reshaping, re-amplifying, and retiming of the bi-directional 10 Gbps serial data by integrating two independent Clock and Data Recoveries (CDRs), two DSPLL-based Clock Multiplier Units (CMUs), and data re-timers in both transmit and receive directions. The DSPLL-based CMU and the data re-timer in the transmit direction eliminate the need for external jitter clean up circuitry to achieve compliance with telecom and datacom jitter specifications. The same DSPLL technology minimizes jitter in the receive path ensuring error free operation with ASICs or FPGAs connected via the XFI interface. The Si5040 provides three receive signal quality monitors including analog loss-of-signal (LOS) detection, consecutive identical digit (CID) detection, and a proprietary digital measure of receive eye opening. Comprehensive diagnostics are also supported via two loop back modes as well as pattern generation and check capability on both the receive and transmit data paths. The Si5040 provides industry leading jitter performance for all telecom and datacom protocols between 9.9 and 11.4 Gbps, including OC-192/STM-64, 10 GbE, 10 G Fiber Channel, and their associated forward error correction (FEC) data rates: - OC192/STM64: 9.95 Gbps - 10 Gbps Ethernet LAN PHY: 10.3125 Gbps - 10 Gbps Fibre Channel: 10.51875 Gbps - G.709 OTU2: 10.709 Gbps - 10 Gbps Ethernet + FEC: 11.0957 Gbps - 10 Gbps Fibre Channel + FEC: 11.3176 Gbps To address XFP module space and power constraints, the Si5040 comes in a 5 x 5 mm LGA package and only consumes 575 mW typ.
