Link Electronics SD SDI Black Burst Module, 2.5ppm, 3-Outputs

Under the expert craftsmanship of Link Electronics, the SD SDI Black Burst Module, 2.5ppm, 3-Outputs, is a reliable and advanced sync generator designed for high-performance video synchronization. This innovative module, when genlocking to incoming video, is housed in the SPG-812 chassis, either as an analog 812-OP/C or a digital 812-OP/D genlock module in slot #1.

This high-quality module transmits timing pulses down the motherboard bus, which the 812-OP/B digital black module utilizes to horizontally lock the Phase-Locked Loop (PLL) on the module. It also resets the vertical and horizontal counters within the complex programmable logic devices, aligning all counters with an external reference.

The 812-OP/B digital burst module, equipped with two 2-bit mechanical encoders, offers infinite phasing on both the vertical and horizontal timing. This feature makes the 812-OP/B an ideal reference generator, adept at compensating for any timing offset within the timing chain.

The horizontal and vertical timing information are securely stored in battery backup RAM onboard the microcontroller. This ensures that even if power is interrupted to the chassis, your valuable timing information is preserved. This feature allows for seamless module transfer from one chassis to another without the risk of losing crucial timing data.

The 812-OP/B digital burst module is versatile and can be placed in any slot except the digital/analog audio test set and power supply slot. When positioned in genlock slot #1, the 812-OP/B digital black module assumes the role of the master, applying the correct timing pulses down the motherboard, with all other modules slaving to it.

Please note, the 812-OP/B digital black module cannot genlock to external video when placed in the genlock slot; it can only operate on its internal time base or 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, triggering all modules to switch should a failure occur in the master generator.

In summary, the SD SDI Black Burst Module, 2.5ppm, 3-Outputs, is a durable, high-output sync generator that offers superior performance and reliability, making it a standout choice in the realm of video synchronization equipment.
