com Transmit and Receive T1 BOC SSM Messages with Receive Message Change of State and The DS26504 is a building-integrated timing-supply Validation Indication (BITS) clock-recovery element.
It also functions as a § Transmit and Receive E1 Sa(n) Bit SSM basic T1/E1 transceiver.
The receiver portion can Messages with Receive Message Change of State recover a clock from T1, E1, 64kHz composite clock Indication (64KCC), and 6312kHz synchronization timing § Crystal-Less Jitter Attenuator with Bypass Mode interfaces.
In T1 and E1 modes, the Synchronization for T1 and E1 Operation Status Message (SSM) can also be recovered.
The § Fully Independent Transmit and Receive transmit portion can directly interface to T1, E1, or Functionality 64KCC synchronization interfaces as well as source § Internal Software-Selectable Receive and the SSM in T1 and E1 modes.
The DS26504 can Transmit Side Termination for translate between any of the supported inbound 75Ω/100Ω/110Ω/120Ω/133Ω synchronization clock rates to any supported § Monitor Mode for Bridging Applications outbound rate.
