XRT6165

Codirectional Digital Data Processor
Data Sheet

Description

The XRT6165 is a CMOS device which contains the digital circuitry necessary to interface both directions of a 64kbps data stream to 2.048Mbps transmit and receive PCM time-slots. The XRT6165 and the companion XRT6164 line interface chip together form a CCITT G.703 compliant 64kbps codirectional interface.

The XRT6165 contains separate transmit and receive sections. The transmitter transforms 8-bit serial data from a 2.048Mbps time-slot into an encoded 64kbps data stream. The receiver, which performs the reverse operation, decodes the 64Kbps data, extracts a clock signal, and then outputs the data to a 2.048Mbps time-slot. The XRT6165 provides features which allow the repetitions and deletions of both received and transmitted data as clock skews and transients occur.

Features

  • Low Power CMOS Technology
  • All Receiver and Transmitter Inputs and Outputs are TTL Compatible
  • Transmitter Inhibits Bipolar Violation Insertion for Transmission of Alarm Conditions
  • Alarm Output Indicates Loss of Received Bipolar Violations
  • Up to 125ms Variance of Data Transfer Timing in Both Transmit and Receive Paths Allows Operation in Plesiochronous Networks
  • Both Receiver and Transmitter Perform Byte Insertion or Deletion in Response to Local Clock Slips
  • Pb-Free, RoHS Compliant Versions Offered

Application

  • CCITT G.703 Compliant 64kbps Codirectional Interface
  • Performs the Digital and Analog Functions for a Complete 64Kbps Data Adaption Unit (DAU) When Used With the XRT6164

The best way to determine this is to go to maxlinear.com and type the part into the search function. At or near the top of the results you should see something that looks like:
 
 
 

In this example, we looked for XRA1201. Click on part number header or on the link at the bottom of the result.  This brings you to the product page. For example:

 
 
 

Click on Parts & Purchasing, highlighted with the blue arrow above. The screen changes to:

 
 
 

Notice the status column and the “Show obsolete parts” link.  A legend tells you the definition of the different statuses. Click on the “Show obsolete parts” link to see EOL or OBS part numbers along with the Active part numbers, the legend still present:

 
 
 

Another method to find out if a part is OBS or EOL is to click on SUPPORT at the top:

 
 
 

And then Product Change Notifications:

 
  
 

Type the part into the search, and click on one of the part numbers from the drop down menu. Then you can look for the Product Discontinuation Notice, which generally is at the top of the list, for example:

 
 
 

If you see this, it tells you that this particular orderable part has been discontinued and when the last order date is, or was. If you click on the file, then you can view the notice we sent about this if you purchased the part in the recent past. It may also advise of a replacement part. When an orderable part first becomes discontinued, Product Discontinuation Notices are sent are sent to those who have purchased the parts in the recent past, if purchased directly, with a dated opportunity to place a last order.
