Abstract

A crosspoint switch including a switch matrix modules and programming features. A switch matrix modules include input lines tied to inputs of the switch through precompensation networks. The programming features include user initialization states and reduced and grouping command configuration operations.

Claims (12)

1. A crosspoint switch unit comprising:

a first set of transmission lines configured to receive a signal;

a second set of transmission lines selectively coupled to the first set of transmission lines;

an amplifier chain coupled to inputs of the first set of transmission lines; and

a tunable input signal equalization circuit coupled to the amplifier chain;

wherein the tunable input signal equalization circuit is configured so as the impedance of the tunable input signal equalization circuit is tuned to the frequency response characteristics of the amplifier chain, thereby reducing noise in the signal and improving the performance of the amplifier chain.

2. The unit of claim 1 further comprising a monolithic integrated circuit substrate and wherein the first and second set of transmission lines are coupled to the substrate.

3. The unit of claim 1 further comprising a monolithic integrated circuit substrate and wherein the input signal equalization circuit is fabricated on the substrate.

4. The unit of claim 1 , wherein the amplifier chain comprises a differential signal path.

5. The unit of claim 1 , wherein the tunable input signal equalization circuit is configured such that the bandwidth of the amplifier chain is increased.

6. The unit of claim 1 , wherein the tunable input signal equalization circuit is tuned such that the power consumption of the amplifier chain is decreased.

7. The unit of claim 1 , wherein the amplifier chain is coupled between the first set of transmission lines and the tunable input signal equalization circuit.
