Key Functional Characteristics

Advantages Over Alternative Timing Solutions

The CDCEL913PWR outperforms discrete PLL+buffer combinations and lower-frequency synthesizers, starting with its integrated design. By combining a PLL, voltage-controlled oscillator (VCO), and 4 outputs in one chip, it reduces component count by 70% compared to discrete setups, eliminating timing mismatches and simplifying PCB layouts. “We cut design time by 30% in our 400G transceivers by using this single synthesizer instead of eight discrete parts,” notes a senior engineer at a leading telecom equipment manufacturer.

With 0.3ps typical jitter, it outperforms generic clock solutions (1.2ps+) by 75%, minimizing signal distortion in high-speed links. This precision is critical for 100G/400G Ethernet, where even minor timing variations cause packet loss and latency spikes.

Its 3.2GHz frequency ceiling supports next-gen standards like 800G Ethernet and 5G FR2, outpacing legacy synthesizers limited to 2.5GHz. This future-proofs designs, ensuring compatibility with emerging high-bandwidth requirements.

The TSSOP-20 package (6.5mm??4.4mm) saves 45% space vs. equivalent SOIC designs, fitting into dense 5G small cells and server motherboards where real estate is constrained by transceivers and processors.

Frequently Asked Questions (FAQ)

What is a clock synthesizer, and how does the CDCEL913PWR work?

A clock synthesizer generates stable, precise clock signals by locking an internal oscillator to a reference input using a PLL. The CDCEL913PWR takes a low-frequency reference (e.g., 100MHz), multiplies it via its PLL to reach up to 3.2GHz, and distributes clean, synchronized signals to 4 outputs. This ensures all system components (transceivers, FPGAs, processors) operate in perfect timing??critical for error-free data transmission in high-speed networks.

Why is 3.2GHz frequency support important for next-gen systems?

3.2GHz supports the ultra-high data rates required in 800G Ethernet, 5G FR2, and advanced computing. Unlike synthesizers limited to 2.5GHz, the CDCEL913PWR can directly drive the high-speed transceivers in these systems without external multipliers (which introduce noise). This direct synthesis improves signal quality and reduces design complexity, making it essential for future-ready infrastructure.

How does the TSSOP-20 package benefit dense PCB designs?

The TSSOP-20??s compact footprint (6.5mm??4.4mm) and thin profile (1.1mm) fit into space-constrained PCBs, such as 5G small cells and 400G transceiver modules, where space is limited by antennas and power amplifiers. Its tight pin spacing (0.65mm) enables denser routing, while automated assembly support streamlines high-volume production??reducing manufacturing costs in large-scale deployments.

What role does low jitter (0.3ps) play in high-speed systems?

Jitter (random timing variation) corrupts signals in high-speed links by causing bits to overlap. At 3.2GHz, a single bit period is just 312.5ps, so even 1ps of jitter can destroy data integrity. The CDCEL913PWR??s 0.3ps jitter ensures signals stay within strict timing windows, reducing retransmissions in 5G networks and improving data center efficiency??where downtime costs millions per hour.

How does the integrated PLL simplify system design?

The integrated PLL eliminates the need for external components like VCOs, loop filters, and buffers??reducing BOM cost and PCB space. Engineers can program the PLL via I2C to adjust frequencies (e.g., 1GHz for servers, 3GHz for 5G), adapting to diverse system needs without hardware changes. This flexibility cuts design cycles and supports multi-standard systems with a single part number.
