The differential HCSL signalling on both sides means it can distribute a clean PCIe or Ethernet reference clock over board traces without the common-mode noise pickup that plagues single-ended routing. The 250 MHz max frequency sets the upper bound for the reference clock this buffer can pass without distortion. If your FPGA or SoC requires a 200 MHz or 156.25 MHz reference for 10GbE or PCIe Gen3, this part has headroom. The 1:8 ratio lets you drive multiple loads — eight SerDes transceivers, eight clocked ADCs, or a fan-out tree — from a single clean source, saving a secondary PLL or oscillator. Compared to the CDCLVP1204RGTR, which is a 2:4 LVPECL fanout buffer with a 2 GHz ceiling and a narrower -40°C to 85°C range, the CDCDB800RSLR trades top-end speed for wider temperature coverage and a larger fanout count (eight outputs vs four). The HCSL output type is also different — LVPECL requires DC-blocking caps and termination resistors that HCSL avoids, simplifying the BOM. ## Active production — no immediate EOL concern The 6x6 mm VQFN footprint is common enough that board layout guides and stencil apertures for the thermal pad are well-documented.","metaTitle":"CDCDB800RSLR Clock Buffer 1:8 250MHz 48VQFN Texas","metaDescription":"CDCDB800RSLR from Texas Instruments: 1:8 HCSL clock buffer, 250 MHz max, -40°C to 105°C, 48-VQFN (6x6).
