The temperature stable ASNT5090-PQC SiGe IC can be utilized as a high speed 1:2 demultiplexer, and isintended for use in high-speed measurement / test equipment. The IC shown in Fig. 1 can receive a highspeed 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 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 positive
supply (vcc = +3.3V and vee = 0.0V = ground). In case of the positive supply, all I/Os need ACtermination 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 toreduced reliability. Functional performance is specified over the recommended operating conditions forpower supply and temperature only. AC and DC device characteristics at or beyond the absolutemaximum ratings are not assumed or implied. All min and max voltage limits are referenced to ground.
