4. Functional Description
The Si5040 XFP transceiver is a single-chip, bidirectional signal conditioner for use in XFP modules as defined by
the XFP multi-source agreement. The Si5040 includes independent clock and data recovery units (CDRs) and
frequency-agile, jitter-attenuating clock multiplier units (CMUs) in both receive and transmit directions. The receive
path includes a limiting amplifier and a programmable equalizer for direct connection to an optical receiver trans-
impedance amplifier. The transmit path includes an equalizer for direct connection to the XFI channel.
The device provides data-agnostic operation over a continuous range of data rates from 9.8 to 11.35 Gbps.
Typical data rates and associated applications include the following:
9.8304 Gbps: Common Public Radio Interface (CPRI)
9.95 Gbps: SONET OC-192, SDH STM-64, 10 Gbps Ethernet WAN PHY
10.31 Gbps: 10 Gbps Ethernet LAN PHY
10.52 Gbps: 10 Gbps FibreChannel (10 GFC)
10.70 Gbps: OTN OTU-2 (G.709)
11.09 Gbps: 10 Gbps Ethernet LAN PHY with 255/237 FEC coding
11.32 Gbps: 10 Gbps FibreChannel with 255/237 FEC coding
Serial control and status monitoring is supported with either an SPI-like or I
2
C serial interface.
