GS12190中文资料Configurable 12G UHD-SDI Reclocking Adaptive Cable Equalizer/Cable Driver数据手册Semtech规格书

描述 Description

The GS12190 is a low-power, configurable multi-rate reclocking Cable Equalizer/Cable Driver supporting rates up to 12G UHD-SDI. It can be configured to equalize or drive signals over 75Ω coaxial cable. It includes DC restoration to compensate for the DC content of SMPTE pathological test patterns. Since the GS12190 is a reclocking device, extremely low output jitter is achievable even at extended cable/trace lengths. The device supports SMPTE ST 2082-1 (12G UHD-SDI), ST2081-1 (6G UHD-SDI), ST 424 (3G SDI), ST 292-1 (HD-SDI), and ST 259 (SD-SDI) signals and is optimized for performance at 11.88Gbps. In addition to standard SMPTE rates, the device also supports reclocking of DVB-ASI at 270Mbps, and MADI at 125Mbps. Each output has highly-configurable pre-emphasis and swing controls to compensate for long trace and connector losses. Additionally, automatic and user selectable output slew rate control is provided for the Cable Driver output.
