• DCKC: AD1 to AD9 latch phase
Sensor lock
1: Positive phase (rising edge)
0: Reverse phase (falling edge)
• NE
Detected on the positive (or reverse)
phase of the sensor lock signal.
1: Does not encode
0: Does encode
Note: When NE is set to 1, no encoding is performed, and the color difference signal is output from
the CO pin without modulation.
The HD49801FB should normally be used with NE = 0.
• DCE: Digital interface control
1: On
0: Off
• PLLON
Set to 1 when locking externally in NTSC mode.
• GE: Grey code enable
1: Grey code
0: Binary code
• A2 to A16 are for use in test mode, and D6 to D28 should be set to all zeros in advance.
