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.","metaTitle":"CDCP1803RGET Clock Buffer 1:3 800MHz LVPECL 24-QFN","metaDescription":"Texas Instruments CDCP1803RGET fanout buffer accepts CML/HSTL/LVCMOS/LVDS/LVTTL/SSTL-2/VML inputs, outputs LVPECL at 800 MHz.

The input stage accepts LVDS (among other standards), and the output is LVPECL. The device performs the level translation internally, so no external resistor network or translator IC is needed between an LVDS oscillator and an LVPECL clock tree."},{"question":"What is the closest functional second-source to CDCP1803RGET?","answer":"The CDCLVP1204RGTR is a peer from Texas Instruments with a 2:4 fanout ratio, LVPECL output, and a wider input range that includes LVCMOS, LVDS, LVPECL, and LVTTL. It operates up to 2 GHz and uses a 2.375 V supply. The CDCP1803RGET offers a 1:3 ratio and accepts additional input standards (CML, HSTL, SSTL-2, VML) at 3.0–3.6 V. They are not pin-compatible; evaluate the supply voltage and fanout count before cross-referencing."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/CDCP1803RGET","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/CDCP1803RGET when reusing this data.
