    SG-8201CJA: Low jitter, high stability, small size, and programmable, designed specifically for ADAS applications: radar, LiDAR, camera, automotive compliance with AEC-Q100125 ℃ operation, excellent stability and jitter performance make SG-8201CJA an ideal choice for LiDAR and ADAS electronic control units - On May 24, 2022, Seiko Epson Corporation (TSE: 6724, "Epson Crystal Oscillators") began shipping SG-8201CJA samples, which is a new member of Epson's CMOS output, crystal oscillator (SPXO) series for automotive applications SG-8201CJA provides high stability and low jitter, and is a simple packaged SPXO with a typical size of 2.0mmx1.6mmx0.6mm.

The application of SPXO oscillator SG-820CJA in autonomous driving (AD),

For example, in vehicle cameras such as Light Detection and Ranging 3 (LiDAR) and Advanced Driver Assistance Systems (ADAS), due to high radio frequency and high frequency, a reference clock with a frequency range of 100MHz is required for processing speed. In addition, the improvement of AD and ADAS performance has driven the growing demand for clocks with excellent stability and jitter performance, and the demand for small products in all automotive applications is also strong。

SG-8201CJA complies with the AEC-Q1004 standard and can operate in ambient temperatures up to 125 ℃, meeting the requirements of automotive applications and helping to improve the safety and reliability of cars. Epson imported crystal oscillators have also started providing SG-8200CJ and SG-8201C crystal oscillator samples for industrial and consumer applications. With this, Epson has assembled a series of products for consumer, commercial, industrial, and automotive applications

Epson is seeking to leverage its device technology to achieve a smart society. To this end, the company will continue to develop products for automotive applications that require uncompromising accuracy and safety, and improve the performance of customer products. Product features include AD and ADAS related functions such as LiDAR and in car cameras.

1. CMOS output: The output of a semiconductor device (complementary MOS), consisting of a complementary combination of P-type and N-type MOSFETs J is commonly used in digital circuits, where H level is used as the power supply voltage output and H level is used as the ground potential output

2. Jitter: Fluctuations in clock cycles can cause fluctuations in displayed images and bit errors in data transmission

3. LiDAR: A technology in which sensors emit pulsed laser waves that bounce off surrounding objects and return to the receiver. The sensor can measure the distance and instantaneous velocity of an object based on the time required for each pulse to return

AEC-Q100: The Automotive Electronics Council (AEC) is an industry organization that develops standards for the reliability and certification of automotive electronic products. It is formed by the collaboration of the "Big Three" American automakers and major electronic component manufacturers The AEC standard is a de facto global standard that has been widely used as a standard for automotive electronic components

5. Including frequency tolerance, frequency/temperature coefficient, frequency power supply voltage variation characteristics, frequency load variation characteristics, reflow soldering characteristics, and frequency aging (+25 ℃, 1 year)

SG-8201CJA: Compliant with the automotive AEC-Q100 standard, operating at 125 ℃ SG-8201CJA is designed for ADAS applications such as radar, LiDAR, cameras, and high-speed Ethernet, where low jitter and high-precision reference clocks are crucial, with an output frequency of up to 170MHz, suitable for the high RF and high-speed operations required by these advanced automotive systems. In addition, utilizing Epson's internal low-noise decimal NPLL, the phase jitter is only 1.1pstyp. Stability<25?? ppm, The small package size of up to 125 ℃. 2.0x1.6mm can significantly save space, as automotive space is increasingly limited by countless sensors. This programmable crystal oscillator provides fast turnaround time and is very suitable for your product development to mass production using 2016 active crystal oscillators。
