15 Las Palmas de G.C., Dec Fast Fourier Transfor Project (results) ä Comparison with other architectures

16 Las Palmas de G.C., Dec The Crosspoint Switch has 32 data inputs and 32 data outputs. Any input can be multiplexed to any, some or all outputs. Signals in data path are fully differential to minimize duty cycle distortion and achieve an excepcional signal fidelity.  VSC851 Project The switch is configured by sequentially loading each multiplexer’s 5-bit Holding register with the desired input address D[4:0]. When complete, a high pulse is applied to GSTROBE and all new configurations are simultaneously transferred into the switch multiplexers.
