ADI ADCLK944BCPZ-R7 Clock Buffer, High-Speed, LFCSP Package

High-Speed Clock Buffer for Precision Timing Applications

The ADCLK944BCPZ-R7 is a high-performance, ultra-low jitter clock buffer designed to meet the stringent requirements of high-speed data acquisition systems, high-frequency communication infrastructure, and advanced instrumentation. Manufactured by Analog Devices, a trusted name in precision analog and mixed-signal solutions, this device delivers exceptional signal integrity and timing accuracy, making it a preferred choice among engineers and system architects.

With its ability to operate at frequencies up to 7.5 GHz and its low additive jitter performance, this clock buffer is ideal for applications where timing precision is critical. The device is housed in a compact 16-WFQFN package, making it suitable for space-constrained designs without compromising performance.

Why Choose This High-Speed Clock Buffer Over Conventional Solutions?

In high-speed digital systems, clock distribution is a critical factor that directly impacts overall system performance. Traditional clock buffers often introduce significant jitter and signal degradation, which can compromise data integrity and system reliability. The ADCLK944BCPZ-R7 addresses these challenges with its ultra-low additive jitter of just 150 fs (femtoseconds) and high-frequency support up to 7.5 GHz.

Unlike standard clock buffers, this device features differential inputs and outputs, which help minimize noise and improve signal integrity. Its low power consumption and wide operating temperature range also make it suitable for industrial and communication applications where reliability and efficiency are paramount.

Industry experts and design engineers consistently recommend this buffer for its robust performance and ease of integration. According to a senior RF systems engineer at a leading telecom company, “The ADCLK944 series has become our go-to solution for clock distribution in our high-speed backplane designs. Its jitter performance is unmatched in this class.”
