DG2722 Vishay Siliconix 2 Port, USB 2.0 High Speed (480 Mbps) Switch, DPDT Analog Switch DESCRIPTION FEATURES The DG2722 is 2 port high speed analog switch optimized for USB 2.0 signal switching. The DG2722 switch is configured in DPDT. It handles bidirectional signal flow, achieving a 900 MHz - 3 dB bandwidth, and a port to port crosstalk and isolation at - 49 dB. Processed with high density sub micron CMOS, the DG2722 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 DG2722 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). Latch up current is 300 mA, as per JESD78, and its ESD tolerance exceeds 8 kV. Packaged in ultra small miniQFN-10 (1.4 mm x 1.8 mm x 0.55 mm), it is ideal for portable high speed mix signal switching application. As a committed partner to the community and the environment, Vishay Siliconix manufactures this product with lead (Pb)-free device termination. The miniQFN-10 package has a nickel-palladium-gold device termination and is represented by the lead (Pb)-free “-E4” suffix to the ordering part number. The nickel-palladium-gold device terminations meet all JEDEC standards for reflow and MSL rating. As a further sign of Vishay Siliconix's commitment, the DG2722 is fully RoHS complaint. • Halogen-free according to IEC 61249-2-21 Definition • Wide operation voltage range • Low on-resistance, 7 (typical at 3 V) • Low capacitance, 6.5 pF (typical) • 3 dB high bandwidth: 900 MHz (typical) • Low bit to bit skew: 40 pS (typical) • Low power consumption • Low logic threshold: V • Power down protection: D+/D- pins can tolerate up to 5 V when V+ = 0 V • Logic (S and OE) above V+ tolerance • 8 kV ESD protection (HBM) • Latch-up current 300 mA per JESD78 • Lead (Pb)-free low profile miniQFN-10 (1.4 mm x 1.8 mm x 0.55 mm) • Compliant to RoHS Directive 2002/95/EC APPLICATIONS • Cellular phones • • • • • • Portable media players PDA Digital camera GPS Notebook computer TV, monitor, and set top box FUNCTIONAL BLOCK DIAGRAM AND PIN CONFIGURATION 8 V+ 9 S 10 HSD1- 7 6 Control OE HSD1+ miniQFN-10L 5 HSD2+ 4 HSD2- 3 GND Rx 1 Top View Document Number: 68379 S11-1430-Rev.
