mitsubishi ics (tv) M52779SP vif, sif, video, chroma, deflection for pal/ntsc 1 description the M52779SP is a single-chip semiconductor integrated circuit to process signals of a color tv. circuits to process video if, sound if, video, color, and de?ction signals, a i 2 c bus control circuit, and d/ a are build in this device. this ic can be used not only for popular-type tv sets but also for middle-class tv sets. combined with a secam chroma decoder, the m52325ap, this device can process signals of every type of tvs in the world by discriminating them fully automatically. features a built-in i 2 c bus control circuit makes it possible to reduce the number of peripheral parts and rationalize production lines. various ?ters (trap, bpf, y-dl, rgb clamp) are build in this ic. pll detection system is introduced to process video if and voice if. furthermore, aft coil is not necessary. dl aperture control color signal frequency and vertical frequency of tvs of every type can be discriminated fully automatically. horizontal/vertical countdown system v-ramp output rgb output built in y/c sw application pal/ntsc ctv recommended operating condition supply voltage................................................v8, 24=5v, v9, 20=8v rated supply voltage........................................v8, 24=4.75 to 5.25v v9, 20 =7.6 to 8.4v maximum output current.............................................5.0ma (pin13) pin configuration (top view) outline 52p4b 52 49 50 51 1 4 3 2 48 5 47 6 44 9 43 10 42 11 41 12 13 14 40 39 7 8 46 45 15 38 16 37 17 36 18 35 19 20 34 33 21 32 22 31 23 24 30 29 25 28 26 27 M52779SP aft out limiter in rf agc out if agc filter vif gnd vif in vif in vif v cc h v cc ramp agc scl scp out h out sda h osc afc 1 filter i ref +ramp out -ramp out hi v cc r out g out b out vcd v cc b in contrast cont. video out video apc filter vco vco fm direct out ext audio in audio out - (r-y) in - (b-y) in - (r-y) out secam ref. - (b-y) out x-tal 4.43 sync sep in y sw out vcd gnd tv in chroma apc filter ext in audio bypass x-tal 3.58 fast blk killer filter r in afc2 filter g in
