Vishay Siliconix

2 Port, USB 2.0 High Speed (480 Mbps) Switch,

DPDT Analog Switch

FEATURES

DESCRIPTION

•

Halogen-free according to IEC 61249-2-21

Definition

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

V_BUSat 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 (V_IH= 1.3 V/min). Latch up current is

300 mA, as per JESD78, and its ESD tolerance exceeds

8 kV.

•

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

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.

•

Portable media players

PDA

Digital camera

GPS

Notebook computer

TV, monitor, and set top box

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.
