The IC shown in Fig. 1 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 aselector 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. The logic isshown in Table 1.
Table 1. Truth Tablec d0 d1 out0 X 000 X 111 0 X 01 1 X 1
As a 2:1 serializer, the IC can receive high speed input data signals into d0p/d0n and d1p/d1n andeffectively multiplex them into a double frequency rate NRZ output data signal by using a high speed
input clock signal on its selector signal inputs cp/cn. The signals should be aligned as shown in Fig. 2. To
ensure both maximum timing margins and low output signal jitter, limit the amount of jitter on the inputsignals (D0, D1, and C) to only a few picoseconds.

Fig. 2. Input Signal Timing Diagram

The common-mode voltage levels of the input clock signals can be adjusted using an external analog
control voltage applied to the port dcp.
The output data swing is controlled by an external analog control voltage applied to the port ampcrl.
The part’s I/O’s 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 can operate with either negative supply (vcc = 0.0V = ground and vee = −3.3V), or positivesupply (vcc = +3.3V and vee = 0.0V = ground). In case of the positive supply, all I/Os need AC
termination when connected to any devices with 50Ohm termination to ground.

All the characteristics detailed below assume vcc = 0.0V and vee = -3.3V.

ABSOLUTE MAXIMUM RATINGS
Caution: Exceeding the absolute maximum ratings shown in Table 2 may cause damage to this productand/or lead to reduced reliability. Functional performance is specified over the recommended operating
conditions for power supply and temperature only. AC and DC device characteristics at or beyond theabsolute maximum ratings are not assumed or implied. All max voltage limits are referenced to ground.
