CDC2510APWR

Overview

The CDC2510APWR is a high-performance, low-skew, low-jitter phase-lock loop (PLL) clock driver manufactured by Texas Instruments. It operates at a supply voltage of 3 V to 3.6 V and supports a maximum frequency of 100 MHz. The device distributes one clock input to ten outputs within a single bank using a 24-pin TSSOP package. It features integrated series-damping resistors for point-to-point loads and includes an on-chip PLL loop filter. The component is characterized for operation from 0°C to 70°C.

Feature Summary

• Distributes one clock input to a bank of ten outputs with low skew and low jitter characteristics
• Uses a phase-lock loop to precisely align the feedback output to the clock input signal in both frequency and phase
• Includes integrated series-damping resistors to drive point-to-point loads without external components
• Features a single output enable terminal that controls all ten outputs simultaneously

Applications

• Synchronous DRAM applications
• Spread spectrum clock compatible systems
• Clock distribution networks requiring precise phase alignment

Procurement Notes

Verify the current marketing status before procurement as the device may be classified as not recommended for new designs. Confirm the specific ordering suffix matches the required packaging quantity and environmental compliance standards. Ensure the design accounts for the stabilization time required for the PLL to achieve phase lock after power-up or reference signal changes.

Selection Notes

Select this component when a fixed-frequency, fixed-phase reference signal is available at the CLK input to ensure proper PLL synchronization. Consider the 1 ms stabilization time requirement during system initialization. Verify that the load capacitance does not exceed the specified limits for accurate timing performance. Evaluate the NRND status if designing a long-term production system.

Part Context

The CDC2510A belongs to the 2510 series of PLL clock drivers designed for synchronous memory interfaces. It shares functional similarities with other devices in the family but is specifically optimized for distributing a single clock source to multiple synchronous DRAM banks. The 'PWR' suffix indicates the plastic TSSOP package variant.

Replacement Considerations

The datasheet explicitly recommends using the CDCVF2510A as a replacement for this device.
