OUT-OF-BAND TUNER
Package: QFN, 16-Pin, 3mm x 3mm
Product Description
The RFFC0085 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 RFFC0085 consists of an input AGC amplifier, mixer, and a video/AGC
amplifier. This device offers optimum performance with low power con-
sumption and low distortion. This product is RoHS compliant.
