Functional Block Diagram The temperature stable ASNT5190-PQC SiGe IC can be utilized as a high speed 1:2 demultiplexer, and is intended for use in high-speed measurement / test equipment. The IC shown in Fig. 1 can receive a high speed differential data input signal dp/dn and effectively demultiplex it into two high speed differential data output signals q0p/q0n and q1p/q1n by using a high speed differential clock input signal 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. 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 termination when connected to any devices with 50Ohm termination to ground. Different PCB layouts will be needed for each different power supply combination.

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 (assumed vcc). Table 1.
