DESCRIPTION

The TSH511 is a 0.4 to 11 MHz dual FM receiver.

This circuit offers the functions needed for a highly

sensitive infrared HiFi STEREO receiver.

Featuring high input sensitivity and high input dy-

namic range, each receiver integrates a RF

front-end LNA, an intermediate amplifier with 2 ex-

ternal filters, a voltage limiter, a quadrature FM de-

modulator, and finally an audio buffer.

The integrated audio buffers are able to drive di-

rectly a 16 ohms headphone with 20mW.

A SQUELCH circuit mutes both audio amplifiers.

Access pins to each section makes the TSH511

suited for a wide field of applications.

For MONO applications, the STANDBY pin en-

ables one receiver only, reducing the supply cur-

rent.

The TSH511 forms a chipset with the dual trans-

mitter TSH512.

APPLICATIONS

s Infrared HiFi stereo receiver

s Infrared Multimedia Headsets

s Stereo sub-carrier demodulator

s FM IF receiver systems

s Power Line Carrier Intercoms
