PS20060 Datasheet, PDF (1/39 Pages) List of Unclassifed Manufacturers – MOPLL with IF AGC Amplifier Preliminary Information

DESCRIPTION
The PS20060 is a 3 band MOPLL with IF AGC
amplifier. It down-converts the RF channel to a
standard IF followed by filtering and IF AGC
amplification for the digital channel. Each band
consists of a low noise preamplifier / mixer and local
oscillator with an external varactor tuned tank circuit.
An IF level detector is included for control of the
RFAGC. The Take Over Point (TOP) and time
constant are both programmable. The PS20060 has
excellent signal level handling performance in the
presence of high level unwanted signals. All chip
control is via I2C bus.
If higher performance is required, an alternative part,
PS20063 is available with image reject down
conversion.
