BIPOLAR ANALOG INTEGRATED CIRCUIT
μ
PC2775GR/GS
DESCRIPTION
The
μ
PC2775GR/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;
μ
PC2775GR) or 20 pins SOP (small outline
package;
μ
PC2775GS) 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
