Description of Functions

1. Progressive Scan CCD drive pulse generation

• Combining this IC with a crystal oscillator generates a fundamental frequency of 24.5454 MHz.

• CCD drive pulse generation is synchronized with the HD and VD inputs.

Set fCL to 780 fHD and fHD to 525 fVD.

• The various operations are performed by the TRIG, EFS and ESG inputs. (See the following items.)

Detection timing for VD,

TRIG, EFS and ESG

After HD input is detected, the status of VD, TRIG, ESG and EFS is detected during T1.

Do not change the status of VD, TRIG, ESG and EFS during T1.

When input is from a non-synchronized system, the low level period for each pulse should be set to 63.5 µs or

longer to prevent misoperation.
