Agilent Technologies Announces New Voltage Controlled Oscillators for 10 and 40 Gb/s Networking Systems

8/27/2002 - Agilent Technologies announced a new line of voltage controlled oscillators (VCOs) with standard coaxial connectors for 10 Gb/s and 40 Gb/s fiber optic communications systems. Also available are hermetic TO-8 packaged oscillators for 10 Gb/s fiber optic communications. These embedded clocks synchronize data and voice communications systems to operate at U.S.-standard SONET, European-standard STM, and 10 Gb/s Ethernet transmission rates.

Agilent's VCOs perform the multiplexing (MUX), clock data recovery and demultiplexing (DEMUX) clocking necessary for boards and line cards in network routers and long-haul communications systems.

"High-speed optical communications systems require very stringent performance specs for jitter rate, modulation bandwidth and frequency drift," said Bryan Ingram, vice president and general manager of Agilent's Wireless Semiconductor Division. "Agilent's new VCOs meet or exceed our customers' requirements and offer the best combination of size, cost and performance available."

Agilent's VCOs in the hermetic coaxial package have a smaller footprint than competitive DRO (dielectric resonator oscillator)-based VCOs and provide better jitter performance than on-chip VCOs. The TO-8 versions are also hermetically sealed.

The Agilent VCO product line features excellent jitter performance (less than 50 femtosecond) for low bit error rate. Their low frequency drift over temperature and time provides a reliable phase lock, and their wide modulation bandwidth assures that clock and data recovery will meet SONET/SDH specifications. The VCOs are supplied in a compact hermetic metal package with RF connector and measure 0.4 inch (H) x 0.95 inch (W) x 1.18 inch (D), providing excellent reliability, improved thermal conductivity, and reduced size. Hermetic TO-8 oscillators are only 0.2 inch high and 0.5 inch in diameter.

U.S. Pricing and Availability
The approximate pricing for 10 GHz TO-8 VCOs is $160 each, 10 GHz VCOs with coaxial connectors $300 each, 20 GHz VCOs $800 each, and 40 GHz VCOs $1400 each, all in 250-piece quantities. All versions are currently available from Agilent and its distribution partners, with delivery 8 to12 weeks after receipt of order.
