New Abracon White Paper: 156.25MHz Ultra-Low RMS Jitter XOs Performance Study

AUSTIN, TX – Abracon, LLC (Abracon), a leading global manufacturer of frequency control, timing, synchronization, RF, connectivity, and power component solutions, announces the release of a white paper titled "156.25MHz Ultra-Low RMS Jitter XOs Performance Study."

Over time, system clock jitter requirements have become stringent. Most require an upper limit of 200fs RMS jitter over 12kHz to 20MHz bandwidth at 156.25MHz carrier. Recognizing this ever-increasing market demand for ultra-low RMS jitter clocking solutions, Abracon continues its quest in enhancing the performance characteristics of its solutions while simultaneously reducing form factors.

This paper reviews the phase noise and RMS jitter performance characteristics of Abracon’s five key ultra-low jitter timing solutions that are designed to meet the challenging RMS jitter requirements of today’s precision applications requiring data rates of 10, 40, 100, 200 and 400Gbps.

Abracon’s AK2, AX3, AK5 and AK7 ClearClock™ crystal oscillator (XO) devices employ a third overtone crystal solution to satisfy stringent frequency stability-over-temperature requirements. These third overtone ClearClock™ solutions offer superior RMS jitter performance – predominantly exceeding system-level requirements for applications such as optical transceivers and data center architectures, which predominantly employ a 156.25MHz local oscillator with superior phase noise and RMS jitter performance as the system clock in 10G, 40G, 100G and upcoming 400G systems.

The white paper also introduces Abracon’s ASGTX5 series of temperature-controlled crystal oscillator (TCXO) devices that address both over-temperature and long-term stability requirements of Stratum-IV architectures. The ASGTX5 solution meets the all-inclusive total stability requirement of ±32ppm maximum at any carrier frequency between 15.0MHz and 2.1GHz. This series is ideally suited for systems that either require stringent frequency accuracy, high carrier frequency [such as 1.00GHz] or CML differential output. 

All five offerings detailed in this white paper are in stock and available via Abracon’s global distribution network.
