Description and Introduction

HIGH FREQUENCY PLL CLOCK GENERATOR The MC12429FN is a phase-locked loop (PLL) clock driver manufactured by Motorola.  

### **Specifications:**  
- **Manufacturer:** Motorola  
- **Type:** PLL Clock Driver  
- **Package:** 28-pin PLCC (Plastic Leaded Chip Carrier)  
- **Operating Voltage:** 3.3V or 5V (depending on variant)  
- **Frequency Range:** Supports high-frequency clock generation (exact range depends on configuration)  
- **Outputs:** Multiple low-skew clock outputs  
- **Function:** Provides synchronized clock signals with low jitter  

### **Descriptions and Features:**  
- Designed for clock distribution in high-speed digital systems.  
- Uses a PLL to synchronize output clocks with an input reference.  
- Low output-to-output skew for precise timing.  
- Suitable for applications requiring multiple synchronized clock signals, such as microprocessors and communication systems.  
- Available in a surface-mount PLCC package for compact PCB integration.  

For exact electrical characteristics and application details, refer to the official Motorola datasheet.

Application Scenarios & Design Considerations

HIGH FREQUENCY PLL CLOCK GENERATOR

Alternative Part Number

  • NB4N527SMNG --: Pin-compatible clock fanout buffer in the same function class, widely available and often used as a drop-in replacement for MC12429 clock distribution parts.
  • CDCLVC1102PW --: Low-jitter clock buffer with similar fanout and supply requirements, suitable functional substitute when the original is unavailable.
  • SY89832UMG --: Precision clock fanout buffer offering comparable performance and package options, a viable alternative from a different series.
  • SY89829UMG --: Low-skew 1:2 differential clock fanout buffer with comparable supply and output levels, suitable as a functional drop-in with minor layout review.
  • MC12148FN --: Same Motorola PLL frequency synthesizer family in a PLCC-28 package, offering comparable synthesizer functionality and pin-compatible footprint for many designs.
  • LMX2316TM --: Integrated PLL frequency synthesizer with similar frequency range and serial programming interface, suitable as a functional replacement in clock generation circuits.
  • ADF4113BRUZ --: Widely available PLL frequency synthesizer with comparable performance and SPI-compatible control, usable as a modern drop-in alternative with minor layout adaptation.
  • ICS12429FN --: IDT (formerly ICS) second-sources the 12429 clock synthesizer function in the same PLCC package, making it a direct functional replacement.
  • CY2292F --: Cypress clock synthesizer with comparable output frequency range and PLCC package, usable as a functional substitute with minor configuration differences.
