DESIGN KIT AVAILABLE  
DS3146/DS3148/DS31412  
6-/8-/12-Channel DS3/E3 Framers  
www.maxim-ic.com  
GENERAL DESCRIPTION  
FEATURES  
The DS3146/DS3148/DS31412 (DS314x) devices  
include all necessary circuitry to frame and format up  
to 12 separate DS3 or E3 channels. Each framer in  
these devices is independently configurable to  
support M23 DS3, C-Bit Parity DS3, or G.751 E3.  
The framers interface to a variety of line interface  
units (LIUs), microprocessor buses, and other system  
components without glue logic. Each DS3/E3 framer  
has its own HDLC controller, FEAC controller, and  
BERT, as well as full support for error detection and  
generation, performance monitoring, and loopbacks.  
Cꢀ6/8/12 Independent DS3/E3 Framers on a Single  
Die  
CꢀFraming and Formatting to M23 DS3, C-Bit Parity  
DS3, and G.751 E3  
CꢀLIU Interface can be Binary (NRZ) or Dual-Rail  
(POS/NEG)  
CꢀB3ZS/HDB3 Encoder and Decoder  
CꢀGenerate and Detect DS3/E3 Alarms  
CꢀIntegrated HDLC Controller for Each Channel  
CꢀIntegrated FEAC Controller for Each Channel  
CꢀIntegrated Bit Error-Rate Tester (BERT) for Each  
Channel
