Description and Introduction

DDR SDRAM MUX The ICS83840AH is a high-performance clock generator manufactured by Integrated Device Technology (IDT). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Input Frequency Range:** 8 kHz to 200 MHz  
- **Output Frequency Range:** 8 kHz to 200 MHz  
- **Outputs:**  
  - 4 differential LVPECL outputs  
  - 1 LVCMOS/LVTTL output  
- **Supply Voltage:** 3.3V ±5%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-Lead TSSOP  

### **Descriptions:**
- The ICS83840AH is a low-jitter, high-performance clock generator designed for applications requiring precise timing.  
- It supports multiple output types, including LVPECL and LVCMOS/LVTTL, making it versatile for various system requirements.  
- The device is optimized for low phase noise and jitter, ensuring reliable performance in communication and networking applications.  

### **Features:**
- **Low Jitter:** <0.7 ps RMS (12 kHz to 20 MHz)  
- **Differential Outputs:** 4 LVPECL pairs with configurable output voltage levels.  
- **Single-Ended Output:** 1 LVCMOS/LVTTL output for general-purpose clocking.  
- **Frequency Flexibility:** Supports a wide input and output frequency range.  
- **3.3V Operation:** Compatible with standard power supplies.  
- **Industrial Temperature Range:** Suitable for harsh operating environments.  

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

Application Scenarios & Design Considerations

DDR SDRAM MUX

Alternative Part Number

  • ICS83840AGLF --: Same ICS83840 clock generator family from IDT with the LF (lead-free) package variant, functionally equivalent and widely available.
  • ICS83840BGLF --: Later revision of the same clock generator series with improved specifications, pin-compatible in most designs.
  • ICS83940AGLF --: Closely related IDT clock distribution part with similar output configuration, usable as a drop-in substitute after verifying output levels.
  • 9DBL411BGLF --: Renesas (which absorbed ICS/IDT) offers this clock buffer with similar differential clock distribution function and comparable output characteristics, making it a strong functional replacement.
  • SI53340-B-GM --: Silicon Labs clock buffer/fanout device with similar low-jitter differential clock distribution capability and comparable package, suitable as a cross-vendor alternative.
  • NB7L14MMNG --: ON Semiconductor differential clock fanout buffer with similar high-speed clock distribution role and comparable electrical performance, usable as a third option.
