Description
The Q48SP12017ERH is an electronic component classified under the IC chips product category. It is a complete selectable E1 or T1 Line Interface Unit (LIU) for short- and long-haul applications. The device generates the necessary G.703 E1 waveshapes in 75Ω or 120Ω applications and DSX-1 line build outs or CSU line build outs of 0dB, -7.5db, -15dB, and -22.5dB for T1 applications. The device also supports AMI, HDB3, and B8ZS encoding/decoding and has a programmable monitor mode for the receiver.
Specifications and features
- Complete E1, T1, or J1 line interface unit (LIU)
- Supports both long- and short-haul trunks
- Internal software-selectable receive-side termination for 75Ω/100Ω/120Ω
- 5V 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
- 16.384MHz, 8.192MHz, 4.096MHz, or 2.048MHz clock output synthesized to recovered clock
- 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
- Multiplexed and nonmultiplexed 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 Q48SP12017ERH electronic component can be applied in short- and long-haul applications requiring a selectable E1 or T1 line interface unit (LIU). It is suitable for use in generating G.703 E1 waveshapes in 75Ω or 120Ω applications and the appropriate line build outs, with and without return loss, for E1 and DSX-1 and CSU line build outs for T1.
Comparison
Advantages- Supports both long- and short-haul trunks
- Internal software-selectable receive-side termination for 75Ω/100Ω/120Ω
- Generates the appropriate line build outs, with and without return loss, for E1 and DSX-1 and CSU line build outs for T1
- 16.384MHz, 8.192MHz, 4.096MHz, or 2.048MHz clock output synthesized to recovered clock
- Loopbacks and PRBS pattern generation/detection with output for received errors
Disadvantages- The Q48SP12017ERH electronic component has limited compatibility with other products other than Intel or Motorola.
- The device requires a 5V power supply, which is not suitable for certain applications.
- The device has limitations in the programmable monitor mode for the receiver.
