QSFP28 (100G) Gearbox /Re-timer FMC Module
(Vita57.1)
10x10G <--> 4x25G
Vita 57 provides a mechanical standard
for I/O mezzanine modules. This standard introduces a methodology that
shall allow the front panel IO of IEEE 1101 form factor cards to be
configured via mezzanine boards. Vita 57 modules have fixed locations
for serial/parallel IOs, clocks, Jtag signals, VCC, and GND. HiTech
Global's Vita 57 modules can be plugged into any Vita 57 compliant
carrier boards.
The FMC-GB-QSFP28 module is powered by Broadcom 100Gbps Gearbox
PHY (BCM82790)that multiplexes and de-multiplexes four 25 Gbps channels to/from
ten 10Gbps channels supporting Ethernet and Optical Transport Networking
(OTN). The module supports one full-duplex 100Gbe port and complies with
100GBASE-CR4/SR4/LR4 for QSFP28 line-card applications. 100GbE Ethernet
support includes CL91 RS FEC as well as CL92 transmit training, and CL73
auto-negotiation.
Test and debug features included in
the Gearbox are PRBS pattern generation and checking, eye monitoring on
all data receive interfaces, programmable loopbacks, as well as JTAG.
Every port on the chip is equipped with an eye monitor. All features are
accessed through an IEEE standard MDIO control interface.

BCM82790 features include:
►Full-duplex,
ten lane-to-four lane Gearbox via IEEE 802.3ba Clause 83 PMA
