DESCRIPTION
The temperature stable ASNT5178-PQC SiGe IC provides extremely low jitter narrowband
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. ASNT5178-PQC canprocess an up to 15GHz RF clock signal and deliver both 0-120ps of adjustable phase delay andoutput signal amplitudes between 0.2V-1.0V through two up to 1GHz external adjustment single
ended 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 any
combination. It operates from a single -4.5V power supply.
