Several million Satellite Set-Top Boxes (STBs) are deployed in many different entertainment
networks around the world today. The standards for each network may vary a little but the
requirements for the tuner in the STB are essentially the same. Each receiver system in the

Filter reference. A resistor to ground from this pin sets the reference current for the tunable
filter. See
I channel output to the demodulator/FEC IC. Can be used balanced or single-ended. Zout
= 1 kΩ//10 pF.
Q channel output to the demodulator/FEC IC. Can be used balanced or single-ended. Zout
= 1 kΩ//10 pF.
I channel DC offset cancellation. A capacitor must be placed between these pins. See

Loop filter. A network with a capacitor in parallel with a series resistor and capacitor
connected from this pin to ground determines the loop filter bandwidth. See

Crystal inputs. A 10.111 MHz, series-resonant, fundamental crystal is placed between
these two pins to create the system clock. See
