Description
The M61140FP is a semiconductor integrated circuit consisting of Tuner signal processing for NTSC color TV and
VCRs.
The circuit includes Mixer circuit in Tuning system, Oscillator circuit, PLL frequency synthesizer and VIF/SIF, which
permits a smaller tuner system.
Features
VIF/SIF
Inter carrier type for NTSC
Coil-less VCO
Adjustment free AFT
High-speed IF AGC
PLL
Low phase noise and High-speed lock-up
Built-in band switch driver (4 port)
I2C bus control
Available for both XO and external reference
Mixer/Oscillator
Built-in U&V Oscillator and mixer
Built-in IF Amplifier (Unbalanced Output)
Application
TV, VCR
Recommended Operating Conditions
Supply voltage range --- 4.75 to 5.25V
Recommended supply voltage --- 5.0V

Charge pump output terminal.
When the phase of the divide
frequency of local is lead
compared with the reference
frequency, the "source" current
state becomes active. If it is lag,
the "sink" current becomes
active. If the phase are the
same, the high impedance state
becomes active.
VIF block power supply.
