DS26514
NOT RECOMMENDED FOR NEW DESIGNS4-Port T1/E1/J1 Transceiver
4-Port Transceiver with Low-Power Consumption and Price
Part Details
- Four Complete T1, E1, or J1 Long-Haul/Short-Haul Transceivers (LIU Plus Framer)
- Independent T1, E1, or J1 Selections for Each Transceiver
- Fully Internal Impedance Match, No External Resistor
- Software-Selectable Transmit- and Receive-Side Termination for 100Ω T1 Twisted Pair, 110Ω J1 Twisted Pair, 120Ω E1 Twisted Pair, and 75Ω E1 Coaxial Applications
- Hitless Protection Switching
- Crystal-Less Jitter Attenuators Can Be Selected for Transmit or Receive Path; Jitter Attenuator Meets ETS CTR 12/13, ITU-T G.736, G.742, G.823, and AT&T Pub 62411
- External Master Clock Can Be Multiple of 2.048MHz or 1.544MHz for T1/J1 or E1 Operation; This Clock is Internally Adapted for T1 or E1 Usage in the Host Mode
- Receive-Signal Level Indication from -2.5dB to -36dB in T1 Mode and -2.5dB to -44dB in E1 Mode in Approximate 2.5dB Increments
- Transmit Open- and Short-Circuit Detection
- LIU LOS in Accordance with G.775, ETS 300 233, and T1.231
- Transmit Synchronizer
- Flexible Signaling Extraction and Insertion Using Either the System Interface or Microprocessor Port
- Alarm Detection and Insertion
- T1 Framing Formats of D4, SLC-96, and ESF
- J1 Support
- E1 G.704 and CRC-4 Multiframe
- T1-to-E1 Conversion
The DS26514 is a 4-port framer and line interface unit (LIU) combination for T1, E1, J1 applications. Each port is independently configurable, supporting both long-haul and short-haul lines. The DS26514 single-chip transceiver (SCT) is software and pinout compatible with the 8-port DS26518. It is nearly software compatible with the DS26528 and its derivatives.
