CDCP1803MRGETEP

Overview

The CDCP1803MRGETEP is an enhanced product 1:3 LVPECL clock buffer with a programmable divider, manufactured by Texas Instruments. It distributes one differential clock input to three LVPECL differential outputs with low skew. The device supports signaling rates up to 800 MHz and operates within a supply voltage range of 3 V to 3.6 V. It features a 24-terminal QFN package (4 mm × 4 mm) and is characterized for operation from -55°C to 125°C. Key electrical parameters include a maximum propagation delay of 600 ps and typical output skew of 15 ps.

Feature Summary

• Distributes one differential clock input to three LVPECL differential outputs
• Programmable output divider for two LVPECL outputs (÷1, ÷2, ÷4, ÷8, ÷16)
• Low-output skew of 15 ps (typical) and max propagation delay of 600 ps
• Supports wide common-mode range inputs including LVDS, CML, HSTL, and single-ended signals

Applications

• Defense applications requiring controlled baseline and traceability
• Aerospace systems utilizing military temperature ranges (-55°C to 125°C)
• Medical applications needing extended product life cycle
• High-speed clock distribution networks driving 50-Ω transmission lines

Procurement Notes

Verify the LIFEBUY status indicated in the Package Option Addendum, as this signifies the device will be discontinued. Confirm that the specific ordering suffix MRGETEP aligns with the required military temperature grade and QFN-RGE package configuration before finalizing procurement plans.

Selection Notes

Select this component when low-skew LVPECL distribution with programmable division is required for high-frequency signals up to 800 MHz. Ensure the design accommodates the 3 V to 3.6 V supply range and utilizes the VBB pin for single-ended input biasing if necessary. Verify PCB thermal via requirements to manage junction temperature effectively.
