Lost detail, noisy color, and jittery data overlay (OSD) are common problems encountered when driving video through long coaxial cables. CAB pre-compensates for cable losses with adjustable voltage gain, high/low frequency boost, and a convenient cable length control. Terminals are provided for an off-board voltage regulator to power your camera module. These features, combined with high drive capability and robust video output circuit protection, make this little board a perfect match for any remote video system that has to work through long cable.  At only 1.50" x 2.25" in size, CAB easily fits inside most environmental camera housings. At just $150.00 single quantity, CAB also fits most budgets.

Physical:

CAB dimensions are 1.5"(W) x  2.25"(L), and approximately 0.75"(H) at the heat sink tab of the output amplifier IC.

Power Supply:

Input: +24VDC nominal (30V MAX). Power supply current is 35mA without an external regulator. CAB provides regulated +12VDC (up to 200ma with adequate heat sinking) camera power output, with an external (customer-supplied) 7812 or equivalent regulator IC. Transient surge protection is provided at the power supply input pins.

Video I/O:

CAB accepts 1Vpp composite NTSC or PAL video from a camera module or other nearby video source. A 75 ohm input termination is provided. Depending on compensation control settings, CAB launches up to 10Vpp into 75ohm coaxial cable. CAB's robust video output amplifier circuit is protected against transient surges and thermal overload.

Cable Length Compensation:

Cable length, high frequency, low frequency, and gain adjustments are provided, to compensate various types of coaxial cable up to lengths of a thousand feet or more.
