DLL IP Cores for UMC

Sign in required. Page 2 and beyond are available to signed-in users.

Delay Locked Loop (DLL) IP cores are essential timing components in modern SoC and ASIC designs, enabling precise clock alignment and delay control.

Unlike PLLs, DLLs do not generate new frequencies but instead adjust the phase of a reference clock, making them ideal for clock distribution, timing calibration, and interface synchronization.

This catalog allows you to compare DLL IP cores from leading vendors based on jitter performance, lock time, power consumption, and process node compatibility.

Whether you are designing high-speed interfaces, memory subsystems, or timing-critical digital systems, you can find the right DLL IP for your application.

What is a DLL (Delay Locked Loop)?

A Delay Locked Loop (DLL) is a feedback-based timing circuit used to align the phase of an output clock with a reference clock in SoCs and ASICs.

Instead of generating new frequencies like a PLL, a DLL adjusts delay elements to achieve precise phase alignment.

Main functions of DLL IP

Clock phase alignment

DLLs ensure that clock signals are aligned across different parts of a chip, reducing timing errors and improving synchronization.

Delay control

DLL IP provides fine-grained delay adjustment, enabling precise control of signal timing.

Jitter reduction

DLLs help minimize timing variations, improving signal integrity in high-speed systems.

Timing calibration

DLL IP is used to compensate for process, voltage, and temperature (PVT) variations, ensuring consistent timing performance.

Key features of DLL IP cores

  • Accurate phase alignment
  • Fast lock time
  • Low jitter performance
  • Fine delay resolution
  • Robust operation across PVT variations

How to choose DLL IP

Selecting the right DLL IP depends on your timing requirements:

Frequently asked questions about DLL IP cores

What is a DLL?

A Delay Locked Loop aligns the phase of a clock signal with a reference clock using delay elements.

What is the difference between DLL and PLL?

A DLL adjusts delay for phase alignment, while a PLL generates new frequencies and controls phase and frequency.

Where are DLL IP cores used?

They are used in memory interfaces, high-speed interfaces, and timing-critical systems.

Why use a DLL instead of a PLL?

DLLs offer lower jitter and simpler design for phase alignment without frequency synthesis.

How do I choose DLL IP?

You should consider delay resolution, jitter performance, lock time, and power consumption.
