Description and Introduction

4 CHANNEL E3/DS3/STS-1 JITTER ATTENUATOR, STS-1 TO DS3 DESYNCHRONIZER The **XRT71D04IV** is a quad T1/E1/J1 short-haul line interface unit (LIU) manufactured by **EXAR Corporation**. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** EXAR  
- **Type:** Quad T1/E1/J1 Short-Haul Line Interface Unit (LIU)  
- **Interface Standards:** Supports T1 (1.544 Mbps), E1 (2.048 Mbps), and J1 (Japanese standard)  
- **Package:** 64-pin LQFP (Low-Profile Quad Flat Package)  
- **Operating Voltage:** 3.3V  
- **Operating Temperature Range:** Industrial (-40°C to +85°C)  
- **Compliance:** Meets ITU-T G.703, G.704, G.706, G.823, and ANSI T1.403 standards  

### **Descriptions:**
- The **XRT71D04IV** integrates four independent LIUs in a single chip, reducing board space and power consumption.  
- It provides full transmit and receive functionality for T1/E1/J1 applications.  
- Includes jitter attenuators, line build-out (LBO) control, and programmable pulse shaping.  
- Supports both short-haul and long-haul applications with configurable line impedance.  

### **Features:**
1. **Quad-Channel Integration:** Four independent LIUs in one package.  
2. **Programmable Line Termination:** Supports 75Ω (E1) and 100Ω (T1/J1) line impedances.  
3. **Jitter Attenuation:** On-chip jitter attenuators for improved signal integrity.  
4. **Line Build-Out (LBO):** Adjustable transmit levels for different cable lengths.  
5. **Diagnostic Features:** Loopback modes (local, remote, analog) for testing.  
6. **Low Power Consumption:** Optimized for power-sensitive applications.  
7. **Industrial Temperature Support:** Operates reliably in harsh environments.  
8. **Integrated BERT (Bit Error Rate Test):** Optional built-in test pattern generation and detection.  

This device is commonly used in telecommunications equipment, including routers, multiplexers, and access concentrators.
