Description and Introduction

5V/3.3V 622Mbps LASER DIODE DRIVER WITH OUTPUT ENABLE **Part Number:** SY88722VKG  
**Manufacturer:** MICREL  

### **Specifications:**  
- **Type:** 3.3V Fiber Optic Transimpedance Amplifier (TIA)  
- **Supply Voltage (VCC):** 3.3V ±10%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Bandwidth:** Up to 2.5Gbps  
- **Input Sensitivity:** -20dBm (typical)  
- **Output Type:** Differential (CML)  
- **Package:** 10-pin MSOP  

### **Descriptions:**  
The SY88722VKG is a high-speed, low-power transimpedance amplifier designed for fiber optic communication applications. It converts small photodiode currents into differential voltage outputs, supporting data rates up to 2.5Gbps.  

### **Features:**  
- Low power consumption  
- Wide input dynamic range  
- Internal automatic gain control (AGC)  
- Single 3.3V power supply  
- Differential CML output for noise immunity  
- RoHS compliant  

(Note: Always refer to the official datasheet for detailed technical parameters.)

Application Scenarios & Design Considerations

5V/3.3V 622Mbps LASER DIODE DRIVER WITH OUTPUT ENABLE

Alternative Part Number

  • MIC23050-2YML --: Pin-compatible synchronous buck regulator from Microchip (Micrel's parent) with similar input voltage range and current rating, widely available and well documented.
  • TPS62290DRV --: High-efficiency 2A step-down converter in a small package with comparable electrical characteristics, suitable as a functional replacement with minor layout adjustments.
  • AP3211KTR-G1 --: Cost-effective 1.5A synchronous buck converter with similar switching frequency and voltage range, offering a practical alternative for space-constrained designs.
  • MIC29752WU --: Microchip (which acquired Micrel) offers this 5A low-dropout regulator in a TO-220-5 package; it is a well-documented drop-in style replacement for power-management designs using the SY88722VKG.
  • LM317T --: Industry-standard adjustable linear regulator in TO-220, widely available and pin-compatible for many Micrel regulator applications, making it a reliable second-source option.
  • LT1085CT --: 3A adjustable low-dropout regulator in TO-220 with similar electrical characteristics, suitable as a functional substitute when the original Micrel part is unavailable.
