DESCRIPTION
The temperature stable ASNT5031-PQC SiGe IC provides extremely low jitter broadband signal
amplitude control capability between its input and output signal ports and is intended for use inhigh-speed measurement / test equipment. ASNT5031-PQC can process an up to 17Gbps data
signal and deliver output signal amplitudes between 0.0V-1.0V through the up to 100MHz
external adjustment of its differential tuning port. The part’s I/Os support the CML logic
interface with on chip 50Ω termination and may be used differentially, AC/DC coupled, singleended, or in any combination. It operates from a single ±5.0V power supply.
