800 MHz LVPECL fanout with multi-standard input flexibility
The CDCP1803RGET is a 1:3 fanout buffer from Texas Instruments that accepts a wide range of input standards — CML, HSTL, LVCMOS, LVDS, LVTTL, SSTL-2, and VML — and delivers a single LVPECL output at frequencies up to 800 MHz. This input flexibility means the same part can sit behind a variety of clock sources without external level translators, simplifying the clock tree layout on mixed-signal boards.
Input-to-output mapping and differential path
The device provides a 1:3 ratio of differential inputs to differential outputs, with both input and output paths fully differential. This preserves signal integrity over the 800 MHz bandwidth, critical for jitter-sensitive applications like ADC sampling clocks or FPGA reference distribution.
Package and footprint considerations
Housed in a 24-VFQFN with exposed pad (supplier package 24-VQFN, 4x4 mm). The 0.50 mm pitch QFN demands careful solder-paste stencil design and a controlled reflow profile to avoid bridging.
Lifecycle and sourcing posture
No end-of-life notification or successor has been issued. Standard TI distribution channels carry the part; procurement can be quoted against BOM quantities through our desk.
