64 kHz composite-clock transceivers

11 August 2004 Telecoms, Datacoms, Wireless, IoT

Dallas Semiconductor's DS26502 and DS26503 are 64 kHz composite-clock transceivers. The DS26502 is a building-integrated, timing-supply (BITS) clock-recovery element that supports the following popular frequencies: 64 kHz timing interface, 2048 kHz and 6312 kHz (Japanese) synchronisation interfaces, and the standard T1/E1/J1 interfaces. Basic framing and formatting are also provided in the T1/E1/J1 operating modes. The DS26502 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. 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 64 kHz composite-clock functionality.
