Epson Automotive Crystal Oscillator Enables High-Performance FPGA Computing

In modern high-performance computing and communication systems, the FPGA clock tree serves as the core hub for timing control, and its stability directly determines system signal integrity. Current mainstream solutions adopt a "crystal oscillator + clock generator + FPGA" architecture, where the choice of reference clock source is critical. Compared to traditional industrial-grade crystal oscillators, automotive-grade crystal oscillators are AEC-Q100 certified, achieving frequency stability of ±20ppm and phase jitter below 1ps within an extreme temperature range of -40°C to +125°C, providing a purer clock source for high-speed SerDes interfaces. Their vibration resistance is improved by more than five times, effectively avoiding clock drift caused by mechanical stress, making them perfectly suited for harsh environmental applications such as automotive computing platforms.

In FPGA clock tree design, the 33.33MHz automotive-grade crystal oscillator, with its precise frequency characteristics, serves as an ideal reference clock for high-speed interfaces such as PCIe Gen3/4 and DDR4. This frequency can be multiplied via a PLL to generate common clock frequencies like 100MHz and 125MHz, and its integer frequency division relationship avoids fractional spurs. Its core advantages are reflected in three aspects: first, the full-temperature frequency deviation is controlled within ±30ppm, ensuring a bit error rate below 10^-12 for high-speed serial links; second, the startup time is less than 6ms, accelerating the system power-on synchronization process; third, it supports spread spectrum modulation, which can reduce EMI radiation by 6dB through ±2% spreading. For example, in ADAS domain controllers, this oscillator can provide synchronous clocks for the FPGA's MIPI CSI-2 interface, ensuring frame synchronization accuracy for multi-camera data acquisition.

Epson’s X1E0003410500 is a 33.33MHz automotive-grade crystal oscillator housed in a ceramic package (size 3.2×2.5mm) with an operating voltage of 3.3V±5%. Based on Epson’s proprietary SG-8101 technology platform, it achieves frequency stability of ±20ppm within a temperature range of -40°C to +125°C, with an aging rate controlled at ±3ppm/year. Its key parameter advantages are shown in the table below:

The device incorporates a built-in temperature compensation circuit, maintaining stable oscillation even in -40°C low-temperature environments. It supports three-state output control, enabling rapid switching between multiple clock sources. In FPGA clock tree applications, it can be paired with clock generators like the CDCE906 to provide reference clocks for FPGA series such as Xilinx UltraScale+ or Intel Stratix 10.
