CDCU877ANMKT

Application Specific Clock/Timing Overview

The CDCU877ANMKT is a 1.8-V phase-locked loop (PLL) clock driver manufactured by Texas Instruments. It functions as a zero-delay buffer, distributing one differential clock input to ten double data rate (DDR II) outputs. The device supports a maximum output frequency of 340 MHz and operates within a supply voltage range of -500 mV to 2.5 V. It features low static phase offset of ±50 ps and consumes 500 uA of working power current. The component is housed in a BGA-Microstar-Junior-52 package with dimensions of 7x4.5 mm. It is designed for surface mount installation and operates between -40 C and +85 C.

Application Specific Clock/Timing Procurement Notes

Verify the specific suffix ANMKT against the official datasheet to confirm pinout and electrical characteristics match your design requirements. Check for obsolescence status or lifecycle changes directly from Texas Instruments documentation before finalizing procurement plans. Ensure compatibility with your board's thermal and mechanical constraints.

Application Specific Clock/Timing Selection Notes

Select this component when a low-skew, zero-delay buffer is required for DDR II interfaces. Confirm that the 52-BGA package fits your PCB layout constraints. Verify that the 1.8-V operating voltage aligns with your system's power rails and that the temperature range meets your environmental specifications.

Application Specific Clock/Timing Part Context

The CDCU877ANMKT belongs to the CDCU877B series of clock drivers. It is part of Texas Instruments' portfolio of timing solutions designed for high-speed digital applications. The device integrates PLL functionality to clean and distribute clock signals with minimal jitter and skew, making it suitable for complex system-on-chip designs.

Application Specific Clock/Timing Replacement Considerations

Consult the official Texas Instruments replacement guide for verified substitute part numbers. Cross-reference pinouts and electrical parameters with alternative models such as the CDCU877RTB or CDCU2A877 only if explicitly documented as compatible replacements.
