DESCRIPTION
The temperature stable and broadband ASNT1122-KMC SiGe IC is a high isolation selector
switch that is intended for use in high-speed measurement / test equipment. The switch routs oneof 4 single-ended CML inputs (“d0”, “d1”, “d2”, “d3”) to its differential CML output“outp/outn” while effectively blocking the other data inputs with high isolation. Selection of aspecific data input is controlled by two digital control signals “sel1” and “sel2” in accordancewith Table 1. Duty cycle of the output signal is controlled by external analog voltage “vbias”.
