DS21Q50  
Quad E1 Transceiver  
www.maxim-ic.com  
GENERAL DESCRIPTION  
FEATURES  
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 75ꢀ coax and  
120ꢀ 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.
