CDCLVP1204RGTR

Overview

The CDCLVP1204RGTR is a high-performance, low-skew, low-additive-jitter differential clock buffer manufactured by Texas Instruments. It features a 2:4 fanout ratio with differential inputs and LVPECL outputs. The device supports multiple input signal types including LVDS, LVPECL, HSTL, HCSL, LVCMOS, and LVTTL. It operates on a single supply voltage ranging from 2.375 V to 3.6 V and achieves a maximum output frequency of 2 GHz. Packaged in a 16-VQFN (3x3 mm) exposed pad format, it is designed for surface mount applications within an operating temperature range of -40°C to +85°C.

Feature Summary

• Supports 2:4 differential fanout with LVPECL outputs
• Compatible with LVDS, LVPECL, HSTL, HCSL, LVCMOS, and LVTTL inputs
• Maximum operating frequency of 2 GHz
• Low additive jitter and low skew characteristics

Applications

• High-speed communication equipment
• Network routers and switches
• Test and measurement devices

Procurement Notes

Verify the specific package variant matches the 16-VQFN (3x3 mm) requirement. Confirm that the LVPECL output logic levels are compatible with the downstream receiver inputs. Ensure the power supply voltage remains within the 2.375 V to 3.6 V range during operation. Check thermal dissipation requirements for the exposed pad design in the final assembly.

Selection Notes

Select this component when a low-jitter 2:4 distribution solution is required for high-speed serial links. It is suitable for systems needing compatibility with various input standards like LVDS or LVCMOS while driving LVPECL loads. Consider the 16-VQFN package size for space-constrained PCB layouts. Verify that the 2 GHz frequency limit meets the system's clock speed requirements.

Part Context

This part belongs to the CDCLVP series of clock buffers from Texas Instruments. It is specifically engineered for applications demanding precise timing and low noise performance. The RGTR suffix indicates the tape and reel packaging configuration for automated assembly processes.

Replacement Considerations

Consult official Texas Instruments documentation for verified pin-to-pin or functional equivalents. Cross-reference specifications such as output drive strength, input compatibility, and package dimensions before substitution.
