The HXR14450 is a quad-channel, low-power, linear transimpedance amplifier (TIA) with an integrated clock and data recovery (CDR) unit. It is a member of the family of optical receiver transmitter array (ORTA) products for high-speed optical interconnects. It is based on PAM4 modulation for next-generation Datacom applications. The HXR14450 integrates a linear transimpedance pre-amplifier, linear post-amplifier, CDR unit, and a versatile output stage in one chip for higher density and lower power consumption applications.
