Agilent Technologies introduces surface-mount voltage controlled oscillators for 40-Gbit/sec systems

January 2, 2002--Agilent Technologies Inc. has introduced a new family of surface-mount (SMT) voltage controlled oscillators (VCOs) for next-generation high-speed 40-Gbit/sec fiber-optic communications systems. The devices synchronize data and voice communications systems to operate at U.S.-standard SONET or European-standard STM transmission rates.

Agilent Technologies Inc. has introduced a new family of surface-mount (SMT) voltage controlled oscillators (VCOs) for next-generation high-speed 40-Gbit/sec fiber-optic communications systems. The devices synchronize data and voice communications systems to operate at U.S.-standard SONET or European-standard STM transmission rates.

Agilent's VCOs perform multiplexing and demultiplexing clocking and enable manufacturers to meet the stringent low-jitter performance specifications necessary for line cards in network routers and long-haul communications systems, claims the company. The compact size of VCOs will enable network equipment manufacturers to design more tightly integrated boards and line cards for 40-Gbit/sec systems.

Agilent's SMT VCOs deliver standard SONET frequencies of 19.906 GHz and 39.813 GHz, with differential outputs, making them compatible with the MUX and DEMUX ICs for 40-Gbit/sec applications. They use Agilent's silicon bipolar and GaAs PHEMT technologies, and operate at 5-V bias with a 0- to 5-V tuning range. They are also available at slightly higher frequencies for systems using forward error correction (FEC), and can be packaged with SMA/K-connectors.

Agilent is shipping engineering samples of the VTO-1990-SMD (19.906 GHz) and the VTO-3981-SMD (39.813 GHz) surface-mount VCOs to select customers. The VTO-1990-SMD is priced at $500 in high volume. The VTO-3981-SMD is $650 in high volume. Both VCOs are also available in coaxial packages and are expected to be available for general sampling by first quarter 2002.
