DESCRIPTION
The ISG510065 is a downconverter designed to be used as
an Out-of-Band Tuner for use in CATV set-top box and Digital
Cable Ready TV applications. The ISG510065 consists of an
input AGC amplifier, mixer, and a video/AGC amplifier. This
device offers optimum performance with low power consump-
tion and low distortion. There are two Package Options MLP
28 and TSSOP 20.
