Texas Instruments triple rate (SD/HD/3G) SDI demonstration board showcases the LMH0340 serializer,LMH0341 deserializer, LMH0344 equalizer, LMH1981 sync separator, LMH1982 clock generator withgenlock and the DS25CP104 cross-point switch. There are many advantages to using the TexasInstruments chipset that include superior performance, reduced cost using inexpensive FPGAs such asthe Xilinx S - Demonst SMPTE-Compliant SDI Out Jittr Using LMH1982 & Virtx-5 GTP Xmittr (Rev. A)PDF, 3.1 Mb, Revisión: A, Archivo publicado: abr 26, 2013
As 3-Gbps serial digital interface (SDI) gains adoption in professional and broadcast video equipment to enable fast-frame 1080p HD video over a single link, the need for flexible and high-performance video clock generation becomes critical to reliably transmit and receive triple-rate (3G/HD/SD) SDI video. This is especially true for multi-channel video equipment using SDI serializers and deserial
