DS3141
Single/Dual/Triple/Quad DS3/E3 Framers
Industry's Smallest, Lowest Cost DS3/E3 Framers for Up to Four Separate Channels
Part Details
- One/two/three/four independent DS3/E3 framers on a single die
- Framing and formatting to M23 DS3, C-bit parity DS3, and G.751 E3
- LIU interface can be binary (NRZ) or dual-rail (POS/NEG)
- B3ZS/HDB3 encoder and decoder
- Generate and detect DS3/E3 alarms
- Integrated HDLC controller for each channel
- Integrated FEAC controller for each channel
- Integrated bit error-rate tester (BERT) for each channel
- Large performance-monitoring counters
- Line, diagnostic, and payload loopbacks
- Externally controlled transmit overhead insertion port
- Support external timing or loop-timing
- Framers can be powered down when not used
- 8-bit processor port supports muxed or nonmuxed bus operation (Intel or Motorola)
- 3.3V supply with 5V tolerant I/O
- 144-pin 13mm x 13mm CSBGA package
- IEEE 1149.1 JTAG support
- Features continued on page 6 of the PDF data sheet
The DS3141/DS3142/DS3143/DS3144 devices include all necessary circuitry to frame and format up to four 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.
