Overview

The GN7152 is an integrated CDR and EML laser driver for PON OLT, 10GBase-ER/ZR Ethernet and 8.5Gb/s Fibre Channel applications. It is a highly-integrated, low-power, small-footprint device, that is ideal for small form factor optical modules.

The GN7152 includes optional input equalization, a multi-rate CDR and an EML laser driver. The GN7152 offers a highly-configurable eye shaping feature, including independently programmable rise and fall pre-emphasis, which allows for an optimal electrical and optical output. The GN7152 also offers the option for polarity-invert and output mute.
