CDCE421ARGET Clock Generator IC 1.2GHz 1 24-VFQFN
The CDCE421ARGET is a high-performance, low-jitter clock generator designed for applications requiring precise timing and wide frequency range. Manufactured by Texas Instruments, this device integrates a crystal oscillator with a phase-locked loop (PLL) based frequency synthesizer, providing stable and low-jitter clock outputs.
The CDCE421ARGET supports a maximum output frequency of 1.2 GHz, ensuring compatibility with high-speed systems. The device features two fully-integrated, low-noise voltage-controlled oscillators (VCOs) operating in the 1.750 GHz to 2.350 GHz range. It provides low output jitter, with typical RMS jitter of 380 fs from 10 kHz to 20 MHz. The CDCE421ARGET supports both LVDS and LVPECL output formats, with output frequencies ranging from 10.9 MHz to 1.175 GHz.
CDCE421ARGET Clock Generator Applications
The CDCE421ARGET is ideal for applications requiring high-frequency clock generation with low jitter. It is commonly used in high-speed communication systems, such as Ethernet switches and routers, where precise timing is critical. The device is also suitable for SONET/SDH systems, 1000BASE-T and 10GBASE-R interfaces, and other applications needing low-jitter clock distribution. Its wide output frequency range and support for multiple signaling standards make it a versatile solution for modern communication and data processing systems.
