Product Summary
The M52358P was developed for use with PAL-system VCRs. The M52358P processes variable speed playback signals. The circuit has all signal processing circuits which are necessary to compensate color alignment during a variable speed playback using PAL-system VCRs. The M52358P consists of V-I converting circuit, TH/DL APC, 2-fsc PLL, color alignment detector, replacement burst circuit, AFC(fH), timing pulse generator and fsc phase converter.The M52358P is widely used in PAL-system VCRs.
Parametrics
M52358P absolute maximum ratings: (1)VCC, supply voltage: 6 V; (2)Pd, power dissipation: 400(500) mW; (3)Topr, operating temperature: -20 to 75℃; (4)Tstg, storage temperature: -40 to 125℃; (5)Kθ, thermal derating (Ta≧25℃): 4.0(5.0) mW/℃.
Features
M52358P features: (1)The color alignment compensation system needs no 1H delay line; (2)No adjustment is necessary for AFC(fH), TH/AL APC and 2-fsc PLL; (3)The BPF has 2-fsc and 3-fsc traps (fo: adjusted automatically); (4)A fsc phase converting circuit is built-in. It is controlled by applying a voltage to pin 24 from an external souce; (5)Tuner system: PAL-M (3.58 MHz) and 4.43-MHz NTSC-APL.
