Description and Introduction

Protocol Transparent, 3.3V, 10MHz to 729MHz, Fractional-N Synthesizer The SY87739LHI is a high-speed, low-power 3.3V clock and data receiver manufactured by **MICREL** (now part of Microchip Technology).  

### **Specifications:**  
- **Supply Voltage:** 3.3V ±10%  
- **Data Rate:** Up to **3.2 Gbps**  
- **Input Sensitivity:** **10 mV (typical)**  
- **Differential Input Voltage Range:** **100 mV to 1.2 V (peak-to-peak)**  
- **Propagation Delay:** **400 ps (typical)**  
- **Power Consumption:** **90 mW (typical)**  
- **Operating Temperature Range:** **-40°C to +85°C**  
- **Package:** **32-pin TQFP (Thin Quad Flat Pack)**  

### **Descriptions and Features:**  
- **High-Speed Clock and Data Recovery (CDR):** Supports data rates up to 3.2 Gbps.  
- **Low Power:** Consumes only 90 mW typical.  
- **Wide Input Voltage Range:** Accommodates differential inputs from 100 mV to 1.2 V.  
- **High Sensitivity:** Operates with input signals as low as 10 mV.  
- **3.3V Operation:** Compatible with standard 3.3V systems.  
- **LVDS/LVPECL Compatible Inputs:** Supports differential signaling standards.  
- **On-Chip Termination:** Reduces external component count.  
- **Industrial Temperature Range:** Suitable for harsh environments (-40°C to +85°C).  

This device is designed for high-speed data communication applications, including fiber-optic networks, SONET/SDH, and high-speed backplane interfaces.

Application Scenarios & Design Considerations

Protocol Transparent, 3.3V, 10MHz to 729MHz, Fractional-N Synthesizer

Alternative Part Number

  • CDCM7005RGZT --: Clock generator and jitter cleaner with similar PLL/synthesizer function, widely available and well documented as a drop-in style replacement for clock synthesis applications.
  • LMK04828BISQE --: High-performance clock jitter cleaner and synthesizer offering comparable low-jitter clock generation, suitable when the SY87739LHI is used as a clock source.
  • 8V19N490BDGI --: Clock synthesizer/jitter attenuator with similar functionality and package options, providing a feasible alternative for clock generation designs.
  • ADF4360-7BCPZ --: Integrated PLL frequency synthesizer with VCO, functionally similar to the SY87739L clock synthesis function and widely available.
  • LMX2571SQE --: Low-power PLLatinum fractional-N synthesizer offering comparable clock generation performance and a different series naming.
  • SI5340B-D-GM --: Clock generator/jitter attenuator that can replace the clock synthesis role of the SY87739L with flexible output configuration.
