Vitesse Semiconductor has announced the extension of its VSC8115 Sonet/SDH STS-3/12, OC-3/12 and STM-1/4 clock and data recovery device family with higher performance devices intended to deliver superior high-speed timing signals for Sonet/SDH-based equipment.
According to the company, the new VSC8115-05 and VSC8115-06 are second generation direct replacements for Vitesse’s current VSC8115 family of products. These pin-for-pin and power supply compatible devices are expected to offer all the features of the existing device family, while delivering improved design margin, better jitter transfer, 18% lower power dissipation, and advanced power supply noise rejection.
The VSC8115-05 and -06 are engineered in a small pin compatible 20-pin TSSOP package to provide the same form, fit, and functions as the VSC8115 first generation devices. In the absence of a valid signal, the CDR can be locked to the reference clock, providing the downstream device a keep-alive clock signal to reduce the re-locking time.
Tony Conoscenti, vice president of product marketing for Vitesse Semiconductor, said: The new generation VSC8115-05 and -06 are ideal for use in existing and future designs and extend the availability of this popular clock and data recovery well into the future. With the designer’s needs in mind, we have developed the VSC8115-05 and -06 as flexible, turn-key solutions that accelerate high-performance functionality and industry-leading jitter design at cost-effective price points needed for today’s Sonet/SDH compliant applications.
