DS26503 - T1/E1/J1 BITS Element
The DS26503 is a building-integrated timingsupply (BITS) clock-recovery element.
The receiver portion can recover a clock from T1, E1, and 6312kHz synchronization timing interfaces.
In T1 and E1 modes, the Synchronization Status Message (SSM) can also be recovered.
The transmit portion can directly
