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.

• 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
