M61111FP Datasheet | Hitachi Semiconductor

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) Remended Operating Conditions - Power-supply voltage range: 4.75 to 5.25 V - Remended power-supply voltage: 5.0 V Application - TV, VCR Pin Configuration Video out TV / FM SW Video in Vcc Video det out APC VCO F/B (Defeat) SIF in (Delay Point) Vreg SIF out (US / JP SW) Audio out Audio Level Cont. 1 2 3 4 5 6 7 8 9 10 11 12 24 23 22 21 20 19 18 17 16 15 14 13 EQ AMP F /B IF AGC 2 IF AGC 1 VIF in 2 VIF in 1 GND QIF in ( Inter / Split SW) RF AGC AFT (FM Carrier det) Logic Vcc Ref Signal (3.58/4.00) Logic GND M611 11 FP Rev.1.00, Aug.25.2003, page 1 of 19 Logic GND Audio Level Cont.
