SG-8201CJA Feature Introduction

SG-8201CJA Contribution to Automotive Applications

1. High frequency stability under wide temperature range by temperature compensation function

Compared with existing SPXO SG-8101CGA, this product can adjust the temperature variation up to +125 ℃ and has high stability characteristics over a wide temperature range. SG-8201CJA can achieve stable frequency tolerance even under tough temperature condition (-40 ℃ to +125 ℃) which is required by various automotive applications.

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.

  Phase jitter
(12 kHz to 5 MHz)
SG-8101CGA 43.7 ps​
SG-8201CJA 1.1 ps

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.
