Fig. 1. Functional Block Diagram
The temperature stable and broadband ASNT5150-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 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 is shown in Table 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
qp/qn 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.

POWER SUPPLY CONFIGURATION
The part can operate with either a negative supply (vcc = 0.0V = ground and vee = −3.3V), or a 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.
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).

PACKAGE INFORMATION
The chip die is housed in a custom 24-pin CQFP package shown in Fig. 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.
The part’s identification label is ASNT5150-KMC. The first 8 characters of the name before the dash
identify the bare die including general circuit family, fabrication technology, specific circuit type, and part
version while the 3 characters after the dash represent the package’s manufacturer, type, and pin out
count.
This device complies with the Restriction of Hazardous Substances (RoHS) per 2011/65/EU for all ten
substances.
