Low-jitter, low-noise VCSO meet low BER for high speed 40G and 100G optical networks

Integrated Device Technology Inc. has added a low-jitter, low-noise Voltage Controlled Surface Acoustic Wave (SAW) Oscillator (VCSO) for high-end optical networking and telecom applications.

IDT explains that the IDT M690SDM incorporates an analog frequency multiplier and single-ended RF output with jitter at less than 270 femtoseconds root mean square (rms) integrated across the 20kHz to 20MHz frequency band, available with an output frequency in the 1.5GHz to 2.1GHz range, providing customers a high frequency reference clock with low-jitter, low-noise performance. The IDT M690SDM's performance specifications meet the low bit error ratio (BER) requirements for high speed 40G and 100G board designs used in telecommunications and optical networking applications, helping to drive the development of next generation cloud computing and 4G wireless infrastructure.

"The IDT M690SDM expands our industry-leading timing portfolio by leveraging our core competencies, such as high-performance radio frequency (RF) integrated circuits, SAW technology and discrete RF/microwave design," said Fred Zust, vice president and general manager of the Communications Division at IDT. "By combining these areas of expertise, IDT provides high-performance, feature-rich solutions that easily meet the ultra-low phase noise and jitter requirements of our customers in the telecom and optical networking markets."

The IDT M690SDM provides +10dBm output power. For many designs, this eliminates the need to use an additional amplifier, simplifying the overall bill of materials, and the device is offered in a compact surface mount technology (SMT) package to minimize its footprint and save board area in densely populated enclosures, according to IDT.
