M61111FP
Coil-less VIF/SIF
REJ03F0014-0100Z
Rev.1.00
Aug.25.2003
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
