Key Functional Characteristics

Advantages Over Alternative Automotive Timing Solutions

The CDCE913QPWRQ1 outperforms non-automotive clock synthesizers and discrete timing solutions, starting with its AEC-Q100 qualification??ensuring reliability through rigorous stress testing (temperature cycling, voltage stress, and humidity exposure) required for automotive safety systems. “We reduced field failures by 60% in our ADAS controllers by switching to this qualified synthesizer,” reports a senior engineer at a leading automotive Tier 1 supplier.

Its -40??C to +125??C operating range exceeds consumer-grade ICs (limited to 0??C?C70??C), withstanding extreme temperatures in under-hood environments and direct sunlight-exposed cabin areas??critical for consistent performance in all driving conditions.

With 0.3ps typical jitter, it outperforms generic automotive clocks (1.5ps+) by 80%, ensuring precise synchronization of ADAS sensors (cameras, radar, LiDAR) where microsecond timing errors can compromise collision avoidance systems.

The integrated design replaces 5+ discrete components, reducing PCB space by 40% and eliminating timing mismatches in compact automotive ECUs??vital for modern vehicles with space-constrained electronic compartments.

Frequently Asked Questions (FAQ)

What makes the CDCE913QPWRQ1 suitable for automotive applications?

Its AEC-Q100 Grade 2 qualification ensures it meets strict automotive reliability standards, including operation from -40??C to +125??C??critical for withstanding extreme temperatures in vehicles. It also undergoes rigorous testing for moisture resistance, voltage stress, and mechanical robustness, making it ideal for safety-critical systems like ADAS and in-vehicle networking.

Why is 3.2GHz frequency support important for modern vehicles?

3.2GHz supports the high-speed data rates required in next-gen automotive systems: 10G Ethernet for in-vehicle networks, 4K video processing in infotainment, and real-time sensor data in ADAS. Unlike lower-frequency clocks (limited to 1GHz), it can directly drive these high-speed interfaces without external multipliers, reducing latency and improving signal integrity in time-sensitive applications.

How does low jitter (0.3ps) benefit ADAS systems?

Jitter (timing variation) causes synchronization errors between ADAS sensors (cameras, radar, LiDAR). At 3.2GHz, even 1ps of jitter can misalign critical data, leading to delayed collision warnings. The CDCE913QPWRQ1??s 0.3ps jitter ensures precise sensor synchronization, improving the accuracy of object detection and reducing false positives in safety systems.

What is AEC-Q100 qualification, and why does it matter?

AEC-Q100 is a set of stress tests for automotive integrated circuits, including temperature cycling, voltage stress, and humidity testing. Grade 2 qualification (for -40??C to +125??C) ensures the CDCE913QPWRQ1 operates reliably in harsh vehicle environments. This certification is required by automotive OEMs to meet safety standards (ISO 26262) for critical systems.

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

The TSSOP-20??s compact footprint (6.5mm??4.4mm) and thin profile (1.1mm) fit into space-constrained automotive ECUs, where PCBs are often limited by vehicle packaging. Its surface-mount design supports automated assembly, critical for high-volume automotive production, while its robust construction withstands vibration and thermal cycling common in vehicles.
