Epson Now Shipping Samples of the SG2016 Series of High-Frequency, Low Phase Jitter SPXOs

At 54% smaller than Epson's SG2520 series SPXOs, this series is ideal for high bandwidth optical modules such as 800G transceivers

Seiko Epson Corporation (TSE: 6724, "Epson") has begun shipping samples of a new series of simple packaged crystal oscillators (SPXO) with differential output1. The series includes the SG2016EGN, SG2016EHN, SG2016VGN and SG2016VHN. All have low phase jitter2 in fundamental mode3 and come in small packages measuring 2.0 x 1.6 mm, with a height of 0.63 mm (typ.). Volume production is scheduled to start in the first quarter of 2023 (calendar year).

Future data traffic will increase even further due to the growth of 5G networks and the implementation of the Internet of Things (IoT). To deal with this traffic, optical transmission modules are expected to transition to even higher speeds and larger capacities, from 400 Gbps to 800 Gbps. Next-generation 800 G optical transmission modules will need to be even smaller because they will have a larger digital signal processor (DSP) built in, which will require more space for heat dissipation.

The new oscillators are 54% smaller in cubic volume than their predecessors, Epson's SG2520EGN, SG2520EHN, SG2520VGN, and SG2520VHN. Like their predecessors, they employ an HFF crystal unit4 and a compact oscillator IC engineered by Epson. They also offer the same high frequency, high stability, and low phase jitter. These features make them ideal for next-generation 800 G transmission modules.

As a leader in quartz crystal devices, Epson seeks to use its technology to contribute to the realization of a smart society and will continue to provide crystal device products that meet the needs of all manner of electronic devices and social infrastructure.
