UPC2775GS - FREQUENCY DOWN CONVERTER FOR VHF-UHF BAND TV/VCR TUNER

General Description

The µPC2775GR/GS are Silicon monolithic ICs designed for TV/VCR tuner applications.

These ICs consist of double balanced mixers (DBM), local oscillator, preamplifiers for prescaler operation, IF amplifier, regulator, UHF/ VHF switching circuit, and so on.

Key Features

  • VHF to UHF band operation.
  • Low oscillation frequency drift against supply voltage and temperature fluctuation due to balanced type UHF oscillator.
  • These ICs can be used in single ended or differential IF outputs.
  • Supply voltage: 9 V.
  • Packaged in 20 pins SSOP or 20 pins SOP suitable for surface mounting.

DATA SHEET BIPOLAR ANALOG INTEGRATED CIRCUIT µPC2775GR/GS FREQUENCY DOWN CONVERTER FOR VHF-UHF BAND TV/VCR TUNER DESCRIPTION The µPC2775GR/GS are Silicon monolithic ICs designed for TV/VCR tuner applications. These ICs consist of double balanced mixers (DBM), local oscillator, preamplifiers for prescaler operation, IF amplifier, regulator, UHF/ VHF switching circuit, and so on. These one chip ICs cover a wide frequency band from VHF to UHF bands. These ICs are packaged in a 20 pins SSOP (shrink small outline package; µPC2775GR) or 20 pins SOP (small outline package; µPC2775GS) suitable for surface mounting. So, these ICs enable to produce economical and physically small or high-density VHF - UHF tuner and reduce the tuner development time. FEATURES • VHF to UHF band operation.
