DALLAS Semiconductor, represented in Australia by Arrow Electronics , has released the DS26504, an enhanced building-integrated timing supply (BITS) clock recovery element. It augments the capabilities of the Company's earlier BITS products by adding support for the 64kHz timing interface (GR378 and G.703 Option A and Option B), 2048kHz and 6312kHz (Japanese) synchronisation interfaces, and the standard T1/E1/J1 interfaces.
Other standard supported frequencies include 19.44MHz and 8kHz. Basic framing and formatting are also provided in the T1/E1/J1 operating modes, making this part a versatile solution for composite clock and T1/E1/J1 architectures.
The DS26504 is also a low-cost solution for composite clock transceiver applications. It can translate from any of the supported inbound synchronisation clock rates to any supported outbound rate. No external component changes are required to switch between any of the synchronisation clock rates or the T1, E1 and J1 standards. No relays or switched external components are required and a single master clock supports all operating modes.
It is packaged in a small 64-pin LQFP like its sister BITS products. It is available in commercial (0°C to 70°C) and industrial (-40°C to 85°C) operating temperature ranges.
