TA1318N

TA1318N TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA1318N SYNC Processor, Frequency Counter IC for TV Component Signals TA1318N is a sync processor for TV component signals. TA1318N provides sync and frequency counter processing for external input signals. These functions are integrated in a 24 pin dual-in-line shrink-type plastic package. TA1318N provides I2C bus interface, so various functions and controls are adjustable via the bus. Features Horizontal synchronization circuit (15.75 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: 1.22 g (typ.) Vertical synchronization circuit (525I, 525P, 625I, 750P, 1125I, 1125P, PAL 100 Hz, NTSC 120 Hz) 1 2003-02-19 TA1318N Block Diagram DAC3 24 DAC3 SW TEST DAC3 VD2-OUT 23 INV SW VD1-OUT 22 INV SW SYNC1-IN 21 SYNC SEPA DAC1 20 DAC1 SW DAC1 SYNC2-IN 19 SYNC SEPA Address SW 18 SCL 17 I CBUS Decoder 2 SDA 16 HD2-OUT 15 INV SW Digital GND 14 HD1-OUT 13 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 DAC2 DAC2 SW V Integral Pulse V C/D V-FREQ SW V-SYNC CP SW H/CSYNK 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...
