DS21Q50 Quad E1 Transceiver

The DS21Q50 E1 quad transceiver contains all the necessary functions for connecting to four E1 lines. The on-board Clock data recovery circuitry coverts the AMI/HDB3 E1 waveforms to an NRZ serial stream. The DS21Q50 automatically adjusts to E1 22AWG (0.6mm) twisted-pair cables from 0km to over 2km in length. The device CAN generate the necessary G.703 waveshapes for both 75 coax and 120 twisted-pair cables. The on-board jitter Attenuators (selectable to either 32 bits or 128 bits) CAN be placed in either the transmit or receive data paths. The framers locate the frame and multiframe boundaries and monitor the data streams for alarms. The device contains a set of internal Registers from which the user CAN access and control the operation of the unit by the parallel control port or serial port. The device fully meets all the latest E1 specifications including ITU-T G.703, G.704, G.706, G.823, G.732, and I.431 ETS 300 011, ETS 300 233, and ETS 300 166 as well as CTR12 and CTR4.
