LightABLE28 LL 100G (full duplex)

LightABLE28 LL 100G (full duplex) embedded transceiver

The LightABLE28 LL low profile screw-in module (4.5 mm) mounts to the board via an LGA connector. It is offered as a (4+4)-lane transceiver that operates at 28 Gbps per lane from −40 °C to 85 °C at ultra-low bit error rates of 10-12. The optical module includes equalizers and pre-emphasis to compensate long traces; these features can be turned off for short traces (less than 10 cm) to reduce power consumption. The LightABLE28 LL also offers CDR functions.
