DESCRIPTION

The DG2720 is 2 Port high speed analog switch optimized for USB 2.0 signal switching. The DG2720 switch is configured in DPDT. It handles bidirectional signal flow, achieving a 620MHz - 3 dB bandwidth with 5 pF load, and a port to port Crosstalk and isolation at - 49 dB. Processed with high density sub micron CMOS, the DG2720 provide low parasitic capacitance. Signals are routed with minimized phase distortion and attain a bit to bit skew is as low as 40 pS. The DG2720 is designed for a wide range of operating voltages, from 2.7 V to 4.3 V that can be driven directly from one cell Li-ion battery. On-chip circuitry protects against conditions when either the D+/D- lines are shorted to the VBUS at the USB port. Additionally, logic control pins (S and OE) can tolerate the presence of voltages that are above the supply power rail (V+). The control logic threshold is guaranteed to be (VIH = 1.3 V/min)
