IY02 (LC89960)
1. Overview
The SANYO LC89960 is a 1H delay line for NTSC television systems.
Only an external low-pass filter is required to implement a 1H delay line.
2. Features
• Single 5V power supply.
• 1H delay signal can be obtained with low-pass filter and 3.58MHz clock input.
• Minimum number of external components required because of timing generator, bias generator, output Amp, on
chipped.
• The phase of output signal is reversed to the phase of input signal.
3. Functions.
• 905 stage CCD shift register.
• Timing generator and clock driver for CCD.
• Auto-bias citcuit.
• Sync tip clamp circuit.
• Sample and hold circuit and output Amp.
• 4fsc clock generator with PLL circuit.
• VCO (4fsc) output circuit.
