Description
The IN112525-LC receiver can equalize a 17-20 dB channel insertion loss. The 17dB
channel loss is tested under OIF-28G-VSR-style jitter stress and matching Tx Eq.
The IN112525-LC has up to ~20 dB channel loss performance potential. It needs Tx
+ Rx Eq and controlled system jitter.
The part supports the Ethernet data rates 100GBASE-LR4/ER4 25 Gbps operation as
per P802.3ba (100 Gbps Ethernet striped across four physical lanes). It also
supports OTU4 28 Gbps operation for OTL4.4 (OTU4 striped across four physical
lanes) as defined in ITU Recommendation G.709.
