The Link Electronics LEI-522 SD/SDI/SMPTE Color Bar & Black Burst Generator with Genlock automatically toggles between NTSC or PAL in the Genlock mode depending on the reference input, whereas it defaults to the selected standard in the free run mode. Using FPGA (Field-programmable Gate Array) technology, the generator offers optimum performance for color bar and black burst as well as while flipping between the 2 generated patterns.
Equipped with 10-bit processing, the generator may be set to alternate between black burst and color bar to confirm frame synchronizer freeze for a remote satellite setup. The LEI-522 generator comes with 2 pairs of independently selectable outputs and the timing range for each output (vertical and horizontal) is infinite.
The front panel, 8-character LED display shows the function under adjustment, whereas the 2 push-button switches are for the "Escape" and "Enter" functions. Adjustments can be easily made to the color bar / black burst generator using the front panel control buttons and the rotary encoder.
For timing purposes, the LEI-522 generator receives a reference black burst in the Genlock mode. The generator can also operate as a stand-alone unit with an inactive looping reference in the free run mode. Infinite Genlock vertical and horizontal timing range is suitable for timing the signal into the studio facility as the 2 outputs can be easily adjusted over the horizontal and vertical timing range. VCXO (Voltage-controlled Crystal Oscillator) offers high stability and provides the accuracy necessary for meeting demanding requirements.
Specifically designed for use in 601 SDI digital applications in both 525/60 and 625/50 systems, the LEI-522 generator is compatible with the EIA RS-189A as well as the SMPTE encoded color bar standard.
