Si5040
10 Gbps XFP Transceiver
Description
The Si5040 is a high performance, protocol agnostic
10 Gbps XFP transceiver featuring integrated jitter
attenuating capability based on Silicon Laboratories’ proven
DSPLL technology. 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.
