TA1370FG

TA1370FG TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA1370FG SYNC Processor, Frequency Counter IC for TV Component Signals TA1370FG is a sync processor for TV component signals. TA1370FG provides sync and frequency counter processing for external input signals. These functions are integrated in a 30 pin SSOP-type plastic package. TA1370FG provides I2C bus interface, so various functions and controls are adjustable via the bus. Features Horizontal synchronization circuit (28.125 kHz, 31.5 kHz, 33.75 kHz, 45 kHz) Horizontal and vertical frequency counter Horizontal PLL Accepts 2-level and 3-level sync Accepts both negative and positive HD and VD Clamp pulse output HD, VD output (polarity inverter) Separated sync output Mask for the copy guard signal Weight: 0.63 g (typ.) Vertical synchronization circuit (525P, 625P, 750P, 1125I, PAL 100 Hz, NTSC 120 Hz) 1 2003-02-19 TA1370FG Block Diagram DAC3 30 DAC3 SW TEST DAC3 VD2-OUT 29 INV SW VD1-OUT 28 INV SW NC 27 SYNC1-IN 26 SYNC SEPA DAC1 25 DAC1 SW DAC1 SYNC2-IN Address SW 24 SYNC SEPA 23 SCL 22 I CBUS Decoder 2 SDA 21 NC 20 HD2-OUT Digital GND 19 INV SW 18 NC 17 HD1-OUT 16 INV SW DV2-OUT SW DV1-OUT SW HD2-OUT SW HD1-OUT SW V-Input SW H/VFREQ Counter V-FREQ DET SW Clamp Pulse V C/D V-FREQ SW V-SYNC DAC2 DAC2 SW V Integral CP SW H/CSYNC HD Polarity 2 × fH H-FREQ DET SW H-INPUT SW H-AFC H C/D H-Ramp HVCO H-FREQ SW 1 HD2-IN 2 VD2-IN 3 HD1-IN 4 VD1-IN 5 Analog GND ...
