XRT83L30

Single-Channel T1/E1/J1 Long-Haul, Short-Haul Line Interface Unit with JA & CDR
Data Sheet

Description

Joining Exar’s proven and extensive T1/E1 device family, the company adds three new products. a single-channel XRT83L30, a quad (four-channel) XRT83L34, and octal (eight-channel) XRT83L38. As demand for more bandwidth drives more communications applications – especially from the backbone or Core to the Metro Area Network. New applications need to transfer data over more than 655 feet, and this series extends the range to 6,000 feet. OEM products for this technology include Multi-Service Provisioning Platforms (MSPP), access devices, media gateways, routers frame relay access devices, and wireless base stations.

Product Highlights

The devices support a single bill-of-material for all T1/E1/J1 implementations, as well as all international (North America, Europe, or Japan) line impedances at 75, 100, 110, and 120-ohms, so that manufacturers can build hardware in advance and software configure the product for the particular application at the time of shipment. The family includes tri-state capability on both transmit and receive paths and matched impedance between the primary and back up receive paths. The tri-state capability can eliminate the need for relays in redundancy implementations. It also allows a back up receive channel to be simultaneously brought on-line in the event of a board power failure. A low jitter, on-chip frequency multiplier provides the necessary clocks to the chip. The master clock that feeds the multiplier can be T1, E1, or lower rates that are frequently available on a board such as 8, 16, 56, 64, 128 and 256kHz.

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.
