Functional Block Diagram The temperature stable ASNT5050-KMC 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 shown in Fig. 1 can route one of its differential data input signals d0p/d0n or d1p/d1n to its differential output outp/outn while effectively blocking the other data input. Selection of a specific data input is achieved through an appropriate external DC biasing of the selector signal inputs cp/cn. The logic is shown in Table 1. Table 1. Truth Table c d0 d1 out 0 X 0 0 0 X 1 1 1 0 X 0 1 1 X 1 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 to its differential output outp/outn by using a high speed input clock signal on its selector signal inputs cp/cn. 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, single-ended, or in any combination (see also POWER SUPPLY CONFIGURATION). 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, the input termination provides the required common mode voltage automatically. The differential DC signaling mode is recommended for optimal performance.

In case of the positive supply, all I/Os need AC termination when connected to any devices with 50Ohm termination to ground. Different PCB layouts will be needed for each different power supply combination. All the characteristics detailed below assume vcc = 0.0V and vee = -3.3V. ABSOLUTE MAXIMUM RATINGS Caution: Exceeding the absolute maximum ratings may cause damage to this product and/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 the absolute maximum ratings are not assumed or implied. All min and max voltage limits are referenced to ground. Table 2.
