Lynx Technik yellobrik SPG 1708 Tri-/Bi-Level Sync Pulse Generator with Genlock

The SPG 1708 is a compact, versatile analog sync pulse generator with genlock, designed to provide Tri-Level (HD) and Bi-Level (SD) video sync signals, as well as audio sync outputs. This module is ideal for broadcast and professional video applications requiring precise synchronization. It offers three Tri-Level sync outputs, three Bi-Level sync outputs, and a separate audio sync output that can be configured for 48kHz Word Clock or Digital Audio Reference Signal (DARS). The sync generator boasts an accuracy of 2ppm and is robust and temperature stabilized. Its flexible genlock capability allows synchronization to any SD, HD, or 3G reference input, with full cross-lock functionality and timing lock, even across unmatched standards. Bi-Level and Tri-Level sync outputs and audio sync signals are all frequency locked to the reference, regardless of the selected sync standard for the outputs. Output signals are timing locked if they are in the same frame rate group as the reference. Additionally, a delay in units of output line and pixel can be applied when remotely controlling the SPG 1708 via yelloGUI. :contentReference[oaicite:5]{index=5}
