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
Application
• TV, VCR
