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 dynamic
range, each receiver integrates a RF
front-end LNA, an intermediate amplifier with 2 external
filters, a voltage limiter, a quadrature FM demodulator,
and finally an audio buffer.
The integrated audio buffers are able to drive directly
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 enables
one receiver only, reducing the supply current.
The TSH511 forms a chipset with the dual transmitter
TSH512.
APPLICATIONS
n Infrared HiFi stereo receiver
n Infrared Multimedia Headsets
n Stereo sub-carrier demodulator
n FM IF receiver systems
n Power Line Carrier Intercoms
