Link Electronics Analog Black Burst Module, 2.5ppm, 2x BB & 1x CFI Outputs

From the moment you start genlocking to incoming video, the SPG-812 chassis, equipped with either an analog SPG-812 (OP/C) or a digital SPG-812 (OP/D) genlock module in slot #2, ensures seamless synchronization. This module strategically places timing pulses down the motherboard bus, which the SPG-812 (OP/A1) analog black burst module utilizes to horizontally lock the Phase-Locked Loop (PLL) on the module and reset the vertical and horizontal counters within the complex programmable logic devices.

This process synchronizes all counters with an external reference, making the SPG-812 (OP/A1) analog black burst module an ideal reference generator that compensates for any timing offset within the timing chain. The module features three, 2-bit mechanical encoders that provide infinite phasing on both the vertical, horizontal, and sub-carrier timing.

The SPG-812 (OP/A) analog black burst module stores the horizontal, vertical, and sub-carrier timing information in battery backup RAM onboard the microcontrollers. This feature ensures that the valuable timing information is preserved even if power to the chassis is interrupted, allowing you to move the module from one chassis to another without the worry of losing this crucial data.

The SPG-812 (OP/A) analog black burst module is versatile and can be placed in any slot except for the digital/analog audio test set and power supply slot. When positioned in the genlock slot #1, the SPG-812 (OP/A1) analog black burst module takes on the role of the master, applying the correct timing pulses down the motherboard, and all other modules become its slaves.

Please note, the SPG-812 (OP/A1) analog black burst module cannot genlock to external video when placed in the genlock slot. It operates solely on its internal time base or in free run mode. When running in free run mode, a front panel control adjusts the frequency of the Voltage Controlled Crystal Oscillator (VCXO).

The PCO-818 automatic pulse change-over modules can operate independently or in synchronized operation. Two PCO-818 change-over chassis can be interlinked to trigger all modules to switch in the event of a failure in the master generator. This Analog Black Burst Module, with its 2.5ppm, 2x BB & 1x CFI Outputs, is a robust solution for your video synchronization needs.
