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
V_BUS 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 (V_IH = 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.
