TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic
TA1370FG
SYNC Processor, Frequency Counter IC for TV Component Signals
TA1370FG
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)
Weight: 0.63 g (typ.)
• Vertical synchronization circuit (525P, 625P, 750P, 1125I, PAL 100 Hz, NTSC 120 Hz)
• 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

VD output pin.
Open collector output.
VD1/VD2 input signals are
output from this pin without
synchronization.
Polarity is switched by BUS
write function.
(Note) When HD PHASE will
be changed, synchronized VD
width will change. Use the start
phase of VD.
