Description
The DS21348TN+ is a complete selectable E1 or T1 Line Interface Unit (LIU) designed for both short-haul and long-haul applications. It is a versatile component that can be used in telecommunication interface applications. The DS21348TN+ features adjustable receive sensitivity which automatically adjusts to the incoming signal. It can be programmed for 0dB to 12dB or 0dB to 43dB for E1 applications and 0dB to 30dB or 0dB to 36dB for T1 applications.
Specifications and Features
- Complete E1, T1, or J1 line interface unit (LIU)
- Supports both long-haul and short-haul trunks
- Internal software-selectable receive-side termination for 75Ω/100Ω/120Ω
- 3.3V power supply
- 32-bit or 128-bit crystal-less jitter attenuator requires only a 2.048MHz master clock for both E1 and T1 with option to use 1.544MHz for T1
- Generates the appropriate line build-outs, with and without return loss, for E1 and DSX-1 and CSU line build-outs for T1
- AMI, HDB3, and B8ZS encoding/decoding
- 16.384MHz, 8.192MHz, 4.096MHz, or 2.048MHz clock output synthesized to recovered clock
- Programmable monitor mode for receiver
- Loopbacks and PRBS pattern generation/detection with output for received errors
- Generates/detects in-band loop codes, 1 to 16 bits including CSU loop codes
- 8-bit parallel or serial interface with optional hardware mode
- Muxed and nonmuxed parallel bus supports Intel or Motorola
- Detects/generates blue (AIS) alarms
- NRZ/bipolar interface for TX/RX data I/O
- Transmit open-circuit detection
- Receive Carrier Loss (RCL) indication (G.775)
- High-Z State for TTIP and TRING
- 50mA (rms) current limiter
Application Scenarios
The DS21348TN+ is commonly used in telecommunication systems for both short-haul and long-haul applications. It can be used in various interface applications such as E1, T1, or J1 line interfaces. It supports different line build-outs and provides features like loopbacks, PRBS pattern generation/detection, and in-band loop codes.
Comparison
