BIPOLAR ANALOG INTEGRATED CIRCUIT

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
