The temperature stable and broadband ASNT5153-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/O’s support the CML logic interface with on chip 50Ohm
termination to vcc and may be used differentially, AC/DC coupled, singleended, or in any combination (see also POWER SUPPLYCONFIGURATION). In the DC-coupling mode, the input signal’scommon mode voltage should comply with the specifications shown inRev. 1.1.2

ELECTRICAL CHARACTERISTICS. In the AC-coupling mode, the input termination provides therequired common mode voltage automatically. The differential DC signaling mode is recommended for
optimal performance.
The required input timing diagram is shown in Fig. 2. To ensure both maximum timing margins and low
output signal jitter, limit the amount of peak to peak jitter on the input signals (D0, D1, and C) to only afew picoseconds.
