Description
The M61111FP is a semiconductor integrated circuit built-in the PLL inter-carrier method VIF/SIF dedicated to NTSC.
The circuit includes the VIF amplifier, image waveform detection, APC detection, IF/RF, AGC, VCO, AFT, LOCK
DET, EQ, AF amplifier, limitter, FM waveform detector circuits, and acts as a small tuner.
Features
• Eliminates the need for the VCO coil for intermediate frequency signal processing
• AFT adjustment is not required and flat temperature characteristics is realized
• Reference frequency of 3.58 MHz/4.00 MHz
• Image intermediate frequency US (47.75 MHz)/JP (58 .75 MHz)
• VIF/SIF mute function
• SIF buffer output available
• FM receivable (optional)
Recommended Operating Conditions
• Power-supply voltage range: 4.75 to 5.25 V
• Recommended power-supply voltage: 5.0 V
Application
• TV, VCR
