GX36220
Short-Form Datasheet
2 x 64Gbps Linear TIA
Description
Features
The GX36220 is a dual-channel 64Gbps linear
Trans-Impedance Amplifier (TIA) for 400G/600G
Integrated Coherent Receivers (ICRs).
•
•
•
•
Dual-channel integrated 64Gbps linear TIA
with analog control interface
Differential linear gain: 150–5,000Ω, and
> 30dB dynamic range
> 40 GHz 3dB-bandwidth and adjustable
bandwidth
Automatic and manual gain control, Output
Voltage Control, Peak Detection and
Shutdown functionalities
The GX36220 integrates two TIA signal paths for
I and Q channels. The high-performance, low
power, and compact design of the GX36220 also
enables a small-form factor integrated optical
module such as CFP2 and CFP4.
•
Low THD, cross talk, and power consumption
for covering 64QAM receiver
Typical Applications
•
400G/600G coherent systems with 64Gbps
16QAM/64QAM modulation format
Integrated optical modules for
