Description and Introduction

ASSP Single Serial Input PLL Frequency Synthesizer On-Chip 2.0GHz Prescaler The MB15E05 is a PLL (Phase-Locked Loop) frequency synthesizer IC manufactured by Fujitsu (now part of Spansion). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Manufacturer:** Fujitsu (MB Series)  

### **Specifications:**  
- **Frequency Range:** 10 MHz to 1.1 GHz  
- **Supply Voltage:** 3.0 V to 3.6 V  
- **Current Consumption:** 8 mA (typical)  
- **Prescaler:** Dual-modulus (8/9, 32/33, or 64/65)  
- **Phase Comparator:** Digital phase-frequency detector  
- **Charge Pump Output:** Available for external loop filter  
- **Serial Interface:** 3-wire (Data, Clock, Enable)  
- **Package:** 16-pin SSOP (Shrink Small Outline Package)  

### **Descriptions:**  
- The MB15E05 is a low-voltage, high-frequency PLL synthesizer designed for wireless communication applications.  
- It integrates a programmable divider, phase comparator, and charge pump for frequency synthesis.  
- Suitable for applications such as cellular phones, wireless LAN, and RF transceivers.  

### **Features:**  
- Low power consumption (3V operation)  
- High-frequency operation (up to 1.1 GHz)  
- Programmable reference divider (R-counter)  
- Programmable feedback divider (N-counter)  
- Lock detect function  
- Low phase noise  

This information is based on the manufacturer's datasheet and technical documentation. For detailed electrical characteristics and application circuits, refer to the official datasheet.

Application Scenarios & Design Considerations

ASSP Single Serial Input PLL Frequency Synthesizer On-Chip 2.0GHz Prescaler

Alternative Part Number

  • LMX2316TM --: PLL frequency synthesizer with integrated prescaler, functionally similar to the MB15E05 and widely available as a direct design substitute.
  • ADF4113BRUZ --: Single-chip PLL synthesizer covering similar frequency ranges with comparable serial programming interface, suitable as a drop-in functional replacement.
  • SKY73101 --: Integrated PLL synthesizer/VCO solution usable in similar RF local oscillator designs when board-level redesign is acceptable.
  • LMX2306TM --: PLL frequency synthesizer with similar integer-N architecture and low power consumption, suitable as a functional replacement in many designs.
  • ADF4001BRUZ --: Integer-N PLL synthesizer offering comparable frequency range and charge-pump output, widely used as a cross-reference for MB15E05-class parts.
  • SKY72310 --: Fractional-N/integer-N synthesizer with similar supply voltage and serial programming interface, usable as an alternative with minor loop filter adjustments.
