CDCLVP1204ARGTR

Overview

The CDCLVP1204ARGTR is a prototype, high-performance clock buffer manufactured by Texas Instruments. It functions as a 2:4 differential fanout buffer and multiplexer, generating four LVPECL outputs from one of two selectable inputs (LVPECL, LVDS, or LVCMOS/LVTTL). The device supports a maximum clock frequency of 2 GHz with a maximum propagation delay of 450 ps. It operates on a supply voltage ranging from 2.375 V to 3.6 V and features an industrial temperature range of -40°C to +85°C. The component is housed in a 16-VFQFN package with an exposed pad.

Feature Summary

• 2:4 Differential Buffer with selectable clock inputs via IN_SEL terminal
• Universal input support for LVPECL, LVDS, and LVCMOS/LVTTL signals
• Maximum clock frequency up to 2 GHz with low additive jitter (<100 fs RMS)
• Industrial operating temperature range (-40°C to +85°C)

Applications

• Wireless Communications systems
• Telecommunications and Networking equipment
• Medical Imaging Devices
• Test and Measurement Equipment

Procurement Notes

This specific part number is designated as a PROTOTYPE. Verify current production status and availability directly with Texas Instruments or authorized distributors, as prototype components may have limited supply or different qualification standards compared to mass-production units.

Selection Notes

Select the CDCLVP1204ARGTR for applications requiring low skew (15 ps typical) and low jitter distribution of LVPECL clocks. Ensure proper termination using 50 Ω resistors to (VCC – 2) V for LVPECL outputs. Confirm that the input signal type matches the supported universal inputs and that the PCB layout accommodates the 16-VFQFN package thermal requirements.

Part Context

The CDCLVP1204 series includes variants such as CDCLVP1204RGTT and CDCLVP1204RGTR. These are high-performance clock buffers designed for demanding communication applications. The 'A' suffix in CDCLVP1204ARGTR typically denotes engineering samples or prototypes, distinct from standard production grades.

Replacement Considerations

Direct replacements include CDCLVP1204RGTT and CDCLVP1204RGTR. Verify pin compatibility and electrical specifications before substitution.
