Functional Block Diagram The temperature stable and broadband ASNT1122-KHC SiGe IC is a high isolation selector switch that is intended for use in high-speed measurement/test equipment. The IC shown in Fig. 1 routs one of 4 singleended CML inputs (d0p, d1p, d2p, d3p) to its differential CML output outp/outn while effectively blocking the other data inputs with high isolation. Selection of a specific data input is controlled by two digital control signals sel1 and sel2 in accordance with Table 1. The duty cycle of the output signal is controlled by an external analog voltage vbias. Table 1.

In the first mode, the input signal’s common mode voltage should comply with the specifications shown in ELECTRICAL CHARACTERISTICS. In the second mode, the input termination provides the required common mode voltage automatically. The differential DC signaling is recommended for the optimal performance. POWER SUPPLY CONFIGURATION The part can operate with either negative supply (vcc = 0.0V = ground and vee = −3.3V), or positive supply (vcc = +3.3V and vee = 0.0V = ground). In case of the positive supply, all I/Os need AC Rev. 1.0.2 2 April 2021 Advanced Science And Novel Technology Company, Inc. 2790 Skypark Drive Suite 112, Torrance, CA 90505 Offices: 310-530-9400 / Fax: 310-530-9402 www.adsantec.com 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 shown in Table 2 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 (assumed vcc). Table 2.

The package provides a center heat slug located on its back side to be used for heat dissipation. ADSANTEC recommends for this section to be soldered to the vcc plain, which is ground for a negative supply, or power for a positive supply. Fig. 2.
