It accepts LVCMOS, LVDS, or LVPECL inputs and translates them to LVDS — a common requirement when a system clock source (crystal oscillator, PLL) needs to drive multiple FPGA transceiver banks, SerDes channels, or ADC/DAC clock inputs without degrading signal integrity. The 800 MHz maximum frequency covers most gigabit-class serial interfaces and high-speed memory buses. ## Supply rail and temperature — what they mean for the BOM The supply range is 2.375 V to 2.625 V. The -40°C to 85°C operating range covers industrial enclosures, outdoor telecom cabinets, and factory-floor equipment. ## Two independent 1:8 buffers — layout and fanout planning With two circuits, each providing a 1:8 fanout, the part can distribute two separate clock domains from a single package — useful for splitting a reference clock and a data clock, or for driving separate FPGA banks with independent frequency/phase requirements. The 1:8 ratio per buffer means one input drives up to eight loads; plan the PCB trace length and impedance matching for LVDS routing to avoid skew across the fanout tree. ## Input compatibility — LVCMOS, LVDS, LVPECL The buffer accepts LVCMOS, LVDS, and LVPECL input levels, so it can sit behind a standard oscillator (LVCMOS), a differential PLL output (LVDS), or a legacy LVPECL clock source. The outputs are always LVDS, which is the dominant interface for high-speed clock distribution in modern digital systems. No external level translation is needed at the input — the buffer handles the conversion internally. ## Lifecycle and sourcing posture The CDCLVD2108RGZT is listed as Active with ROHS3 compliance. There is no NRND or LTB signal, so it remains a safe choice for new designs and production BOMs.","metaTitle":"CDCLVD2108RGZT Fanout Buffer, 800 MHz, 1:8 LVDS, 48-VQFN","metaDescription":"TI CDCLVD2108RGZT fanout buffer distributes one clock to eight LVDS outputs at up to 800 MHz.
