Frequently Asked Questions
What is the maximum output frequency of the CDC421A125RGET?
The CDC421A125RGET supports a maximum output frequency of 125 MHz, making it suitable for high-speed clock distribution in FPGAs, networking, and DSP applications that require stable, high-frequency clocking across multiple outputs.
What logic families does the CDC421A125RGET support?
The CDC421A125RGET is compatible with both LVCMOS and LVTTL logic families, operating from a 3.3V supply. This dual-standard compatibility allows it to interface with a wide variety of modern digital ICs without additional level translation.
What package does the CDC421A125RGET come in and what are its dimensions?
The CDC421A125RGET is offered in a 24-pin VQFN (RGE) package, which features an exposed thermal pad for improved heat dissipation. The compact footprint is ideal for space-constrained PCB layouts in embedded and telecom applications.
How many outputs does the CDC421A125RGET provide?
The CDC421A125RGET provides 4 buffered clock outputs from a single input, enabling 1-to-4 clock fanout. This allows one clock source to drive up to four independent clock loads simultaneously with matched propagation delays, simplifying board-level clock distribution.
