HXR14100 - Block Diagram
説明
The HXR14100 single-channel linear Trans-Impedance Amplifier (TIA) is a member of Renesas' Optical Receiver Transmitter Array (ORTA) product family. Together with a PIN detector, the HXR14100 can be used to design a compact linear Receiver Optical Sub-Assembly (ROSA) for the next-generation 200G optical transceivers with advanced modulation schemes in 28GBaud PAM4 data rates.
This TIA operates in a 3.3V supply or 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.
