The **PLL602-03HSC-R** is a high-performance, low-power Clock Frequency Multiplier integrated circuit (IC) developed by Microchip (formerly PhaseLink). It is specifically designed to work with fundamental crystals to produce a high-frequency, low-jitter output. --- ## 1. Technical Specifications The following table summarizes the key electrical and physical parameters of the device: | Parameter | Specification | | :--- | :--- | | **Function** | Clock Multiplier / Frequency Synthesizer | | **Input Frequency** | 12 MHz to 25 MHz (Fundamental Crystal) | | **Output Frequency** | 48 MHz to 100 MHz (4x Multiplier) | | **Package Type** | SOP-8 (Small Outline Package) | | **Operating Voltage** | 3.3V (± 10%) | | **Output Type** | CMOS | | **Operating Temperature** | 0°C to +70°C (Commercial Grade) | | **RoHS Status** | Compliant (Lead-Free) | --- ## 2. Key Features and Internal Components The "PLL" in the part number stands for **Phase-Locked Loop**, which is the core technology used to stabilize and multiply the clock signal. ### Core Architecture * **Crystal Oscillator Circuit:** Designed to drive a standard fundamental crystal without needing external capacitors (in most layouts). * **Phase-Locked Loop (PLL):** Multiplies the input crystal frequency by a factor of 4. * **Output Buffer:** A CMOS output stage capable of driving 15pF loads with fast rise and fall times. ### Performance Benefits * **Low Jitter:** Optimized to provide a stable clock for timing-sensitive applications like networking and digital video. * **Space Saving:** By using a low-frequency crystal to generate a high-frequency clock, it reduces the cost and space required for high-frequency fundamental crystals, which are fragile and expensive. --- ## 3.
