HXR44400数据手册Renesas中文资料规格书

描述 Description

The HXR44400 is an extension of low-power, single-ended input, quad channel linear Trans-Impedance Amplifier (TIA) array, and a member of the Optical Receiver Transmitter Array (ORTA) product family.  Together with an array of PIN detectors or a group of detectors, the HXR44400 can be used to design a compact linear ROSA for the next generation 200G optical transceivers with advanced modulation schemes. HXR44400 support 28GBaud PAM4 applications.

This TIA operates in a 3.3V supply or in a 2.9V supply for low power consumption, providing exceptionally low input referred noise density, wide input optical power range, excellent linearity up to 3mA overload, and a high bandwidth. The chip is designed with the patented adaptive biasing scheme.
