The DS2153Q T1 Single-Chip Transceiver (SCT) contains all of the necessary functions for connection to E1 lines. The onboard clock/data recovery circuitry coverts the AMI/HDB3 E1 waveforms to a NRZ serial stream. The DS2153 automatically adjusts to E1 22 AWG (0.6 mm) twisted-pair cables from 0 to 1.5 km. The device can generate the necessary G.703 waveshapes for both 75-ohm and 120-ohm cables. The onboard jitter attenuator (selectable to either 32 bits or 128 bits) can eliminate jitter, ensuring high-quality reception.
The DS2153Q is an industrial grade single-chip transceiver designed for connection to E1 lines. It contains all necessary functions including clock/data recovery, waveshaping, and framing. The device converts AMI/HDB3 E1 waveforms to a NRZ serial stream and can generate G.703 waveshapes for both 75-ohm and 120-ohm cables.
