TA1318NG

TA1318NG TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA1318NG SYNC Processor, Frequency Counter IC for TV Component Signals TA1318NG is a sync processor for TV component signals. TA1318NG 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. TA1318NG 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) www.DataSheet4U.com 1 2005-09-08 www.DataSheet4U.com TA1318NG Block Diagram DAC3 24 DAC3 SW VD2-OUT 23 INV SW VD1-OUT 22 INV SW SYNC1-IN 21 SYNC SEPA DAC1 20 DAC1 SW 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 TEST DAC3 DV2-OUT SW DV1-OUT SW DAC1 HD2-OUT SW HD1-OUT SW V-Input SW H/VFREQ Counter V-FREQ DET SW Clamp DAC2 Pulse V C/D V-FREQ SW V-SYNC CP SW H/CSYNC DAC2 SW V Integral HD Polarity 2 × fH H-FREQ DET SW H-INPUT SW H-AFC H C/D H-Ramp HVCO H-FREQ...
