It outputs LVDS or LVPECL — the two most common differential signalling standards for high-speed serial links — so it can drive the reference clock on an FPGA, SERDES, or ADC directly without an external translator. We source and quote it per RFQ against your quantity, with lot traceability and visual inspection as standard.","metaTitle":"TI CDCE421RGER Clock Generator, 1.2 GHz, LVDS/LVPECL, QFN-24","metaDescription":"Texas Instruments CDCE421RGER clock generator IC.
