Description and Introduction

3.3V 32-175Mbps AnyRate CLOCK AND DATA RECOVERY Use lower-power SY87700AL for new designs The SY87700LHG is a high-speed limiting amplifier manufactured by **MICREL** (now part of Microchip Technology). Below are its key specifications, descriptions, and features based on factual information:

### **Specifications:**
- **Supply Voltage:** 3.3V ±10%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Data Rate:** Up to 2.7 Gbps  
- **Input Sensitivity:** Typically 5 mV (differential)  
- **Output Swing:** 800 mV (differential, typical)  
- **Propagation Delay:** < 200 ps  
- **Power Consumption:** Typically 150 mW  
- **Package:** 32-pin TQFP  

### **Descriptions:**
- The SY87700LHG is a **DC-coupled, high-speed limiting amplifier** designed for **fiber optic receivers** and other high-speed data communication applications.  
- It provides **signal conditioning** for weak input signals, amplifying them to a consistent output level.  
- The device includes **RSSI (Received Signal Strength Indicator)** functionality for monitoring signal strength.  

### **Features:**
- **Wide Bandwidth:** Supports data rates up to **2.7 Gbps**.  
- **Low Input Sensitivity:** Detects signals as low as **5 mV (differential)**.  
- **DC-Coupled:** Eliminates the need for external AC-coupling capacitors.  
- **RSSI Output:** Provides an analog voltage proportional to input signal strength.  
- **High Gain:** Fixed internal gain of **~50 dB**.  
- **LVDS-Compatible Outputs:** Ensures compatibility with high-speed interfaces.  
- **Single 3.3V Supply Operation:** Simplifies power requirements.  

This information is based on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

Alternative Part Number

  • MC100EP16DG --: Differential receiver/driver in the same high-speed ECL/PECL family class; widely available and functionally similar for clock/data distribution applications.
  • NB6L16DTR2G --: High-speed differential clock/data receiver with similar ECL/PECL signaling support, offering a comparable alternative from a different series.
  • SY100EP16VZG --: Microchip's ECL/PECL differential receiver in the SY100EP series, a different naming series from SY87700 and suitable as a functional replacement.
  • NB6L11DTG --: Differential clock/data driver with similar low-voltage signaling function and pin-compatible footprint, widely available and cost-effective.
  • DS90LV011A --: LVDS driver in a small package offering comparable high-speed differential signaling performance for similar applications.
  • FIN1101K8X --: LVDS repeater/driver with similar signal conditioning role, suitable as a functional substitute when exact matching is not critical.
