HYBRID SWITCH WITH NEGATIVE SIGNAL HANDLING

Description

Features

The IDTHS221P10 is a high-performance hybrid switch

device, combined with hybrid low distortion audio and USB

2.0 high speed data (480 Mbps) signal switches, and

analog switches. When operated with a 1.8 V single supply,

this high performance switch allows audio signal swings

below-ground, allowing the use of a common USB and

audio headphone connector in personal media players and

other portable battery powered devices.

• +1.7 V to +1.95 V single-supply operation (VDDx)

• Low distortion negative signal handling capability with

Ron less than 2 ohm for Audio signal

• Control pin to open all switches and enter low power state

• Cross-talk audio channels (20 Hz to 20 kHz): -110dB

• -3dB bandwidth USB switches: 700 MHz

• Available in µMLP packages – RoHS compliant

The IDTHS221P10 logic SEL control pin is 1.8 V

• Compliant with USB 2.0 short circuit requirements

without additional external components

compatible which allows for control via a standard

µcontroller. With a VDD voltage in the range of 1.7 V to 1.95

V, the device can pass USB 3 V signal sources in the

portable device, with up to 5.5 V tolerant on USB and COM

signal pins. The part has an audio enable control pin to

open all the switches and put the part in a low power state.

• Power off protection on common D+/R, D-/L ports

Applications

• MP3 and other personal media players

• PDA’s

The IDTHS221P10 is available in a small 10-pin µMLP

package.

• Audio/USB Switching

• Cellular and mobile phones
