Functional Block Diagram The temperature stable ASNT6164-KMM linear non-blocking cross-switch 2x2 is intended for use in high-speed systems. The IC shown in Fig. 1 can deliver two different broad-band analog differential signals d0p/d0n and d1p/d1n to two differential outputs q0p/q0n and q1p/q1n with a nominal gain of 0dB. 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. Both controls are very similar and change peaking of the part’s frequency response at high frequencies (above 20GHz). Ief1c has a higher impact on the frequency response and also improves linearity at low control voltages. 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 that can 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. Table 1.

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 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.
