Overview

GN7155B is a combined 10Gbps EML laser driver/clock and data recovery (CDR) with 2.5Gbps burst mode limiting amplifier for XG-PON applications. Transmit eye-shaping technology is combined with a Semtech ClearEdge® CDR to achieve a high quality driver output. A wide dynamic range APC loop supports a wide variety of TOSAs. The burst mode limiting amplifier meets strict XG-PON timing requirements. An integrated ADC with sensors provide digital diagnostic information. Applications for GN7155B include XG-PON optical line terminal (OLT) modules.
