Plus YC in & NTSC Out
IEC-843C, YUV to NTSC or YC
The IEC-843 is a RGB to NTSC encoder with RS-
170A sync generator. The unit also accepts YUV
(BETA or MII) inputs as model IEC-843C. Other
versions are available. The system is a self
contained unit measuring only 1 3/4 inches high
and 8 inches deep. It can be mounted in a
standard 19 inch equipment rack.
The required signal input is RGB, or YUV with or
without sync on the green channel. An external
composite video or black burst input is required to
gen-lock to an external source. The internal sync
generator provides blanking and burst to the
encoder section.

Internal RS-170A Sync Gen.
The IEC-843 provides all sync generator pulse
outputs that conform to the RS-170A specification.
The propagation delay of the encoded signal is
250nS. An internal set of jumpers provide "Y" and
"C" outputs for recording on S/VHS tape recorders.
The IEC-843A provides NTSC and YC outputs
simultaneously. The various configurations of the
unit are explained above.
Front panel controls are: AC ON/OFF, normal lock,
internal lock, PC lock, internal frequency, SC
phase and horizontal phase. The unit operates on
115 VAC and dissipates approximately 15 watts.
