SG-8201CJA: Automotive AEC-Q100 Compliant, 125 ℃ Operation

The SG-8201CJA is designed for ADAS applications such as radar, LiDAR, camera and high-speed ethernet where low jitter and high precision reference clocks are critical.
With output frequencies up to 170 MHz, it is suitable for high radio frequency and high-speed operations required by these advanced automotive systems. Furthermore, utilizing Epson's in-house low noise fractional-N PLL, the phase jitter is only 1.1 ps typ. and stability is <25 ppm up to 125 ℃.

The small package size of 2.0 × 1.6 mm enables crucial space savings as automotive real estate is becoming increasingly limited with the myriad of sensors.

This programmable crystal oscillator is available with quick turn-around time, perfect for your product development to mass production.

2 Low jitter by improving in-house IC performance

Compared with existing SPXO SG-8101CGA, phase noise is improved about 30 dBc/Hz at offset frequency from 100 kHz to 1 MHz, and phase jitter is reduced to about 1/40. SG-8201CJA achieve lower jitter by reducing noise level. It can contribute to the improvement of sensor detection range and resolution.

3 High output frequency by PLL technology

Internal PLL technology enables programming any frequency up to 170 MHz by multiplying the internal crystal’s frequency. SG-8201CJA can support high-speed telecommunication which requires higher output frequency.
