78P2351R Small form-factor STM-1e Line Interface Unit

The 78P2351R is TDK's second generation Line Interface Unit (LIU) for 155Mbit/s electrical SDH interfaces (STM1e). The device is a single chip solution that includes an integrated Clock & Data Recovery in the transmit path for easy, cost efficient NRZ to CMI conversion.

The device interfaces to 75Ω coaxial cable through wideband transformers and can handle over 15dB of cable loss.

By integrating CDR capabilities in the transmit path, the small 78P2351R (7x7mm MLF package) is also ideal for new STM1e Small Form-factor Pluggable (SFP) modules.
