Applications
The CDCEL937PWG4 is used in audio/video consumer electronics, communications equipment, and set-top boxes that require multiple synchronised clock domains derived from a single 32 MHz crystal. Its three independent PLLs allow simultaneous generation of audio sample-rate clocks, video pixel clocks up to 230 MHz, and peripheral interface clocks without external clock buffers or dividers.

Frequently Asked Questions
What is the maximum output clock frequency of the CDCEL937PWG4, and which clock domains can it serve simultaneously?
The CDCEL937PWG4 generates output clocks up to 230 MHz across its three independent PLL outputs, enabling a single IC to simultaneously supply a 27 MHz video reference, a 48 kHz audio master clock, and a 100 MHz peripheral bus clock from one 32 MHz crystal input.
How does the CDCEL937PWG4's triple-PLL architecture reduce external clock components in a set-top box design?
By integrating 3 independent PLLs in a 20-pin TSSOP, the CDCEL937PWG4 replaces three separate clock synthesizer ICs and their crystal networks. This consolidation cuts board area by roughly 60% compared to discrete solutions and reduces BOM cost while maintaining jitter performance below 100 ps RMS on each output.
Is the CDCEL937PWG4 compatible with standard lead-free SMT reflow processes, and what peak temperature does it tolerate?
Yes—the CDCEL937PWG4 is rated for a peak reflow temperature of 260°C, which meets the IPC/JEDEC J-STD-020 profile for lead-free soldering. The 20-pin TSSOP package with 0.65 mm pitch is compatible with standard pick-and-place and reflow ovens used in high-volume consumer electronics manufacturing.
