DG2730
Vishay Siliconix
2 Port, USB 2.0 High Speed (480 Mbps) Switch,
DPDT Analog Switch
DESCRIPTION
The DG2730 is 2 port high speed analog switch optimized for
USB 2.0 signal switching. The DG2730 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 DG2730
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 DG2730 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
DG2730 is fully RoHS complaint.
