Description
The SL2610 is a mixer oscillator intended primarily
for application in all band tuners, where it performs
image reject downconversion of the RF channel to a
standard 36 MHz or 44 MHz IF.
Each band consists of a low noise preamplifier/mixer
and local oscillator with an external varactor tuned
tank. The band outputs share a common low
impedance SAWF driver stage.
Frequency selection is controlled by the on-board I2C
bus frequency synthesizer. This block also controls
four general purpose switching ports for selecting the
prefilter/AGC stages.
