Bus Control Functions

Write Mode (*: Preset)

•

H-FREQUENCY (Horizontal oscillation frequency)

Switches horizontal frequency.

(00): 15.75 kHz

(01): 31.5 kHz

*(10): 33.75 kHz

(11): 45 kHz

•

HD1/VD1-OUT SW (HD1/VD1 output switch)

Switches output from pin 16/28. When set to 00, 01, or 10, outputs HD/VD without synchronization.

When set to 11, outputs HD/VD from the sync circuit. (Note) Synchronized VD width will change, when

HD PHASE will be changed.

*(00): HD1/VD1

(01): HD2/VD2

(10): HD3/VD3

(11): Synchronized HD/VD

•

HD2/VD2-OUT SW (HD2/VD2 output switch)

Switches output from pin 19/29. When set to 00, 01, or 10, outputs HD/VD without synchronization.

When set to 11, outputs HD/VD from the sync circuit.

*(00): HD1/VD1

(01): HD2/VD2

(10): HD3/VD3

(11): Synchronized HD/VD

•

SEPA LEVEL (Sync separation level switch)

Switches sync separation level of pin 24/26. Set values are the levels from sync tip. Sync separation level

is changed according to the ratio of H-SYNC width during 1H period.

*(00): 10IRE

(01): 15IRE

(10): 20IRE

(11): 25IRE (at 1125I/60)

•

DAC1 (DAC1 control)

Controls 2-bit DAC (pin 12).

(00): 1 V

(01): 3 V

*(10): 5 V

(11): 7 V

•

DAC2 (DAC2 control)

Controls 2-bit DAC (pin 25).

*(00): 1 V

(01): 3 V

(10): 5 V

(11): 7 V

•

DAC3 (DAC3 control)

Controls open collector 1-bit DAC (pin 30).

*(0): OPEN (HIGH)

(1): ON (LOW)

•

TEST (Test mode)

Switches DAC1, 2, and 3 outputs. Also used to test IC for shipping.

*(0)

: DAC outputs are used as DAC.

(1): DAC1 outputs V. SYNC to the frequency counter.

DAC2 outputs H. SYNC or C. SYNC to the frequency counter.

DAC3 outputs IC test pulse for shipping.
