as an Out-of-Band Tuner for use in CATV set-top box and
Digital Cable Ready TV applications. The S510065-55Z
consists of an input AGC amplifier, mixer, and a video/AGC
amplifier. This device offers optimum performance with low
power consumption and low distortion. There are two Pack-
age Options QFN 28 and TSSOP 20. The product is RoHS

RF Amplifier
This amplifier provides a maximum gain of 29 dB. The gain is
programmed by applying a DC voltage (from 0 to 3 V) to the
AGC pin, providing 27 dB of range.
Video Amplifier
This amplifier provides a maximum gain of 55 dB. The gain is
programmed by applying a DC voltage (from 0 to 3 V) to the
AGC pin, providing 28 dB of range. The outputs of the video
amp are both open drain and require pull-up inductors to VDD.
Downconversion Mixer
Thisdoublebalancedmixerhas12dBofconversiongain. The
outputs of the mixer are both open drain and require pull-up
inductors to VDD.
Note:
1. TheRFamplifierandvideoamplifierarecontrolledbyasingleAGC
so the overall dynamic range is the sum of the RF amplifier range
and the video amplifier range.
