INDUSTRY'S ONLY 64kHz COMPOSITE-CLOCK TRANSCEIVERS
DALLAS, TX-July 20, 2004-Dallas(R) Semiconductor (NASDAQ: MXIM) introduces the DS26502/DS26503, the industry's first 64kHz composite-clock transceivers. The DS26502 is a building-integrated, timing-supply (BITS) clock-recovery element that supports the following popular frequencies: 64kHz timing interface, 2048kHz and 6312kHz (Japanese) synchronization interfaces, and the standard T1/E1/J1 interfaces. Basic framing and formatting are also provided in the T1/E1/J1 operating modes, making this part an extremely versatile and low-cost solution for composite clock and T1/E1/J1 architectures.
The DS26502 can translate from any of the supported inbound synchronization clock rates to any supported outbound rate. No external component changes are required to switch between any of the synchronization clock rates or the T1, E1, and J1 standards. Additionally, no relays or switched external components are required, and a single master clock supports all operating modes.
The DS26503 supports all the features of the DS26502, with the exception of the 64kHz composite-clock functionality.
These devices come in small 64-pin LQFP packages and both are available in commercial (0 degrees Celsius to +70 degrees Celsius) and extended (-40 degrees Celsius to +85 degrees Celsius) operating temperature ranges. Prices start at $16.85 for the DS26502 and $11.80 for the DS26503 (5000-up, FOB USA). Evaluation kits are available to speed designs.
