The temperature stable ASNT6164-KMM linear non-blocking cross-switch 2x2 is intended for use inhigh-speed systems. The IC shown in Fig. 1 can deliver two different broad-band analog differentialsignals d0p/d0n and d1p/d1n to two differential outputs q0p/q0n and q1p/q1n with a nominal gain of0dB. It can also be used as a two-channel analog mixer/adder of signals d0p/d0n and d1p/d1n. Two lowspeed analog current controls Ief1c and Ief3c are available for bandwidth and peaking adjustments. Bothcontrols are very similar and change peaking of the part’s frequency response at high frequencies (above20GHz). Ief1c has a higher impact on the frequency response and also improves linearity at low controlvoltages. A relatively flat frequency response can be achieved at lower control voltages but it may be not
the best setting for the signal eye.
The assignment of inputs to outputs is performed through the external high-speed ports sel1 and sel2 thatcan be referenced to either vcc or vee. The assignment logic is shown in Table 1. When the low-speed
single-ended control port on2 is set to vcc, it switches the circuit into mixer/adder mode with both inputs
active at the same time.

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. In DC-coupling mode, the input
signal’s common mode voltage should comply with the specifications shown in the ELECTRICAL
CHARACTERISTICS. In AC-coupling mode, the input termination provides the required common mode
voltage automatically.

POWER SUPPLY CONFIGURATION
The part can operate with either negative supply (vcc = 0.0V = ground and vee = −3.6V), or positive
supply (vcc = +3.6V 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 = ground.

ABSOLUTE MAXIMUM RATINGS
Caution: Exceeding the absolute maximum ratings shown in Table 2 may cause damage to this productand/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 theabsolute maximum ratings are not assumed or implied. All min and max voltage limits are referenced toground (assumed vcc).
