SV7102
Low Voltage, High-Speed USB 2.0 Switch
Description
Features
The SV7102 is a high-bandwidth switch specially
Wide operating range: +1.65V ~ +5.5V
USB2.0 (Full Speed) and
designed for switching high-speed USB 2.0 signals
in handset, portables and digital consumer
applications. It offers seamless switching with
extreme low attenuation designed for applications
requiring low bit-to-bit skew and high channel-to-
channel noise isolation, and is fully comppliant with
industry high-speed USB 2.0 standard.
USB 2.0 (High Speed),
legacy USB 1.1
compliant
Wide bandwidth: 810MHz (typ.)
9ns switching transition time
Cross-talk: -45dB at 480Mbps
Off isolation: -40dB at 480Mbps
Low ON-resistance: RON= 4 (typ.)
Extreme low signal propagation delay
Low power consumption
The SV7102 switch features wide bandwidth that
allows minimum edge and phase distortion while
signals passing through. The SV7102 is acting as a
multiplex that multiplexes twol outputs of a USB host
device to one of two corresponding outputs fro
connecting to an external USB device. The switch is
bidirectional, so it can be used as a demultiplex too.

Notes:
1. For max. or min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device type.
2. VDD=+3.0~4.4V, TA = 25°C ambient and maximum loading.
3. Measured by the voltage drop between Y and Dx pin at indicated current through the On-Resistance is determined by the lower of
the voltages on the two (Y, Dx) pins.

Notes:
1.For max. or min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device type.
2.Guaranteed by design.
3.The switch contributes no propagational delay other than the RC delay of the On-Resistance of the switch and the load capacitance. The time
constant for the switch alone is of the order of 0.25ns for 10pF load. Since this time constant is much smaller than the rise/fall times of typical
driving signals, it adds very little propagational delay to the system. Propagational delay of the switch when used in a system is determined by
the driving circuit on the driving side of the switch and its interactions with the load on the driven side.
