25G TIA for PD
Product Overview
The HLR25G0 is a high sensitivity transimpedance amplifier with automatic gain control manufactured in a high volume, large capacity pure CMOS process designed for 25Gbps applications and data rates. The HLR25G0 can be used in multi-rate applications such as CPRI wireless optical networks from 614.1 Mbps up to 24 Gbps and also supporting 10/25 Gbps rates.
Featuring a receiver signal strength monitor, photodiode capacitance range selection and digital configuration options the HLR25G0 is a high performance and versatile receiver solution for next generation 25 Gbps optical receivers.
The HLR25G0 is provided with pre-programmed digital settings optimised for the application package requirement. The HLR25G0A is optimised for 7-pin/COB packaging whilst the HLR25G0B is optimised for lower cost 5-pin TO packages.
The HLR25G0 has been designed to enable ‘industry standard’ assemblies with its small foot print (0.7 mm x 1.05 mm).
