TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic
TA1318AFG
SYNC Processor, Frequency Counter IC for TV Component Signals
TA1318AFG is a sync processor for TV component signals. TA1318AFG provides sync and frequency counter processing for external input signals. These functions are integrated in a 30 pin SSOP-type plastic package. TA1318AFG 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: 0.63 g (typ.)
Vertical synchronization circuit (525I, 525P, 625I, 750P, 1125I, 1125P, PAL 100 Hz, NTSC 120 Hz)
