DESCRIPTION
The temperature stable ASNT5073-KMC SiGe IC provides extremely low jitter broadband
signal phase shifting and amplitude control capability between its input and output signal ports
and is intended for use in high-speed measurement / test equipment. ASNT5073-KMC canprocess an up to 14GHz-28Gbps RF clock/data signal and deliver both 0-140ps of adjustablephase delay and output signal amplitudes between 0.0V-0.8V through two external adjustmentdifferential tuning ports. The part’s I/Os support the CML logic interface with on chip 50Ω
termination and may be used differentially, AC/DC coupled, single-ended, or in anycombination. It operates from a single -3.3V power supply.
