Digital Ground
Serial clock input. When CSB pin is low, then 16-bit serial
data is inputted by controlling micom. Built-in pull-up resistor.
Auto clear pin. If low, then all circuit is reset.
Built-in pull-up resistor.
LC oscillation pin. Standard frequency is 9MHz &
the horizontal start position and the horizontal size are controlled
by the clock of oscillation block.
While pin 6 is low, serial data input is active.
Built - in pull-up resistor
Serial data input pin. Built-in pull-up resistor
LPF gets rid of the color signal in a video input signal.
Clamp input pin of composite video signal of 2Vpp
Analog ground
Phase detect output of analog PLL. Loop filter is formed by PD
OUT and VCO IN.
VCO input pin of PLL
Capacitor node 1 of PLL VCO
Capacitor node 2 of PLL VCO
Resistor node of PLL VCO
5V Analog V
DD
Composite video input pin
When SECAM mode, color signal is mixed in the character level.
Composite video output pin
