Epson SG-8201CJA crystal oscillator

Epson’s SG-8201CJA is a crystal oscillator (SPXO) with CMOS output for automotive applications. Offering high stability and low jitter, the product is a simple packaged SPXO that typically measures 2 x 1.6 x 0.6 mm.

Applications in autonomous driving (AD), such as LiDAR and vehicle cameras in advanced driver-assistance systems (ADAS), require a reference clock with a frequency in the 100 MHz range due to the high radio frequencies and high speeds handled. Moreover, improvement in AD and ADAS performance has fuelled rising demand for clocks that offer better stability and jitter performance. Demand is also strong for smaller products in all automotive applications.

Like its predecessor, the SG-8101CGA, the latest crystal oscillator supports output frequencies as high as 170 MHz for automotive applications, but it has 50% better frequency tolerance and approximately 1/25th the phase jitter. The package footprint and cubic volume are also 64% and 55% smaller, respectively. AEC-Q100 compliant, the product operates at ambient temperatures up to 125°C as required for automotive applications and contributes to automotive safety.
