The temperature stable and broadband ASNT5151-MOD SiGe IC can be utilized as either a high isolation
selector switch or a high speed 2:1 serializer and is intended for use in high-speed measurement / test
equipment. When employed as a selector switch, the IC can route one of its differential data input signals
d0p/d0n or d1p/d1n to its differential output qp/qn while effectively blocking the other data input.
Selection of a specific data input is achieved through appropriate external DC biasing of the selector
signal inputs cp/cn. As a 2:1 serializer, the IC can receive high speed input data signals into d0p/d0n
and d1p/d1n and effectively multiplex them into a double frequency rate NRZ output data signal byusing a high speed input clock signal on its selector signal inputs cp/cn. The common-mode voltage
levels of the input clock signals can be adjusted using the analog control inputs dcp/dcn.
The part’s I/Os support the CML logic interface with on chip 50Ohm termination to vcc and may be useddifferentially, AC/DC coupled, single-ended, or in any combination (see also POWER SUPPLYCONFIGURATION). In the DC-coupling mode, the input signal’s common mode voltage should comply
with the specifications shown in ELECTRICAL CHARACTERISTICS. In the AC-coupling mode, theinput termination provides the required common mode voltage automatically. The differential DC
signaling mode is recommended for optimal performance.

POWER SUPPLY CONFIGURATION
The part operates on a negative supply (vcc = 0.0V = ground and vee = -4.5V)
