Clock and Pixel I/O
CLK
29
26
TTL
Clock. The clock input is TTL-compatible and all pixel data
is registered on the rising edge of CLK. It is recommended
that CLK be driven by a dedicated TTL buffer to avoid
reflection induced jitter, overshoot, and undershoot.

TTL
Blue pixel data inputs. The Blue digital input is TTL-
compatible and registered on the rising edge of CLK.
Controls
SYNC
17
11
TTL
Sync pulse Input. Bringing SYNC LOW, turns off a 40
IRE (7.62 mA) current source which forms a sync pulse on
the Green D/A converter output. SYNC is registered on the
rising edge of CLK along with pixel data and has the same
pipeline latency as BLANK and pixel data. SYNC does not
override any other data and should be used only during
the blanking interval.
Since this is a single-supply D/A and all signals are
positive-going, sync is added to the bottom of the Green
D/A range. So turning SYNC OFF means turning the
current source ON. When a sync pulse is desired, the
current source is turned OFF. If the system does not
require sync pulses from the Green D/A converter, SYNC
should be connected to GND.
BLANK
16
10
TTL
Blanking Input. When BLANK is LOW, pixel inputs are
ignored and the D/A converter outputs are driven to the
blanking level. BLANK is registered on the rising edge of
CLK and has the same pipeline latency as SYNC.
Video Outputs
IOR
36
33
0.714 Vp-p
Red D/A output. The current source outputs of the D/A
converters are capable of driving RS-343A/SMPTE-170M
compatible levels into doubly-terminated 75 Ohm lines.
IOG
35
32
1 V p-p
Green D/A output. The current source outputs of the D/A
converters are capable of driving RS-343A/SMPTE-170M
compatible levels into doubly-terminated 75 Ohm lines.
Sync pulses may be added to the Green D/A output.
IOB

29
0.714 Vp-p
Blue D/A output. The current source outputs of the D/A
converters are capable of driving RS-343A/SMPTE-170M
compatible levels into doubly-terminated 75 Ohm lines.
