The CHD 1812 is a versatile and compact HDMI to SDI converter with integrated frame synchronizer. It is an ideal solution for any application which requires a fully synchronized SDI input from an external asynchronous HDMI source.

The flexible reference sync input will accept any analog video sync format including SD bi-level sync, black burst, colorbars and tri-level HD sync. The sync input is auto detecting and fully cross lock compatible. For example: An SDTV reference can be used to frequency lock an HD HDMI input. If no reference is present, the converter performs a standard asynchronous HDMI to SDI conversion. A pair of stereo analog inputs can be embedded into any AES channel. Audio inputs can be either professional balanced audio with selectable full scale level, or unbalanced consumer line level audio. By default any audio present in the HDMI stream will be embedded into the SDI output or it can be replaced with the external audio signals.

The module is also compatible with the yelloGUI software package, which provides access to a host of additional internal settings including adjustable video delay for timing purposes.

An SDI fiber output is also provided with a variety of plug in SFP options available

HDMI Input

3D compatible input using type A connector

Up to 8 channels embedded audio in HDMI is passed transparently

Reference Input

SDTV: Analog 525 or 625 bi-level sync, black burst or colorbars
HDTV: All tri-level sync standards (exceptions 1080p 50/59.94/60Hz) Cross lock compatible

SMPTE 274M, SMPTE 296M - 75 Ohm BNC connector

Frame Synchronizer

Functional if valid reference is detected, otherwise operates in free run (asynchronous) mode. External audio and HDMI input are frequency locked to external reference, fully cross lock compatible across standards. One frame adjustable delay (in line and pixel increments) using yelloGUI

SDI Outputs

2 x SDI video, 75 Ohm BNC. (both have the same signal - NOT dual link)
SMPTE ST 259M (SDTV), SMPTE ST 292-1 (HDTV 1.5Gb/s)
SMPTE ST 424M (3Gb/S) supporting ST 425-1 Level A and ST 425-2 (3D)<

Multi-standard output.
SDTV (525/625)
720p and 1080p (23.98/24/25/29.97/30/50/59.94/60 Hz)
1080i (50/59.94/60 Hz)

Fiber Output Optional plug in SFP for optical SDI output (see fiber options table)
Audio Inputs Left and right analog audio using 1/4 inch jack plugs

10k Ohm differential balanced input mode with 24,22,20,18,15,12 dBu full scale (selectable)

Unbalanced mode with (line level) at -10 dBV (1/4 inch Jack Plug to RCA connection adapters supplied)

Selectable AES channel for audio embedding (1 through 8) (Overwrites any HDMI embedded audio present in selected channel)

Frequency response: <+/- 0.2dB 20Hz to 20KHz

48kHz A/D sample rate (free run or frequency locked to reference input)

Power +12VDC @ 4W nominal - ( supports 10 - 14VDC input range )
Physical Size: 138mm x 90mm x 22mm (5.43” x 3.54” x 0.86”) including connectors Weight: 230g (8.11oz)
Ambient 5 - 40ºC (41 - 104ºF) 90% Humidity (non condensing)
