The **K1150BACM-R** is a specific electronic component primarily identified as a **Crystal Oscillator**. It is commonly used in telecommunications, networking, and industrial computing to provide a stable clock frequency. Below is a detailed breakdown of its electronic characteristics and specifications. --- ## 1. Core Component Identification | Property | Description | | :--- | :--- | | **Component Type** | Clock Oscillator (SPXO - Simple Packaged Crystal Oscillator) | | **Manufacturer** | Often associated with **Microsemi** or **CTS Electronic Components** (Legacy Series) | | **Package Style** | Through-Hole (DIP-14 or DIP-8 footprint, usually 4-pins used) | | **Termination** | Lead-Free / RoHS Compliant (Indicated by the "-R" suffix) | --- ## 2. Key Specifications While specific datasheets may vary slightly by production year, the "K1150" series generally follows these parameters: ### Electrical Characteristics * **Frequency Range:** Typically ranges from 1.0 MHz to 100.0 MHz (The specific frequency is usually printed on the top of the can). * **Supply Voltage ($V_{cc}$):** Standard **5.0V DC** (±10%). * **Output Logic:** **TTL / CMOS** compatible. This means it can drive standard digital logic circuits directly. * **Stability:** Usually ±50ppm or ±100ppm (parts per million) over the operating temperature range. ### Physical Characteristics * **Case:** Hermetically sealed metal "can" to prevent moisture and electromagnetic interference (EMI). * **Mounting:** Through-hole technology (THT). * **Pin Configuration:** 1. **NC (No Connect)** or Tri-state Control. 2. **Ground (GND).** 3. **Output.** 4. **$V_{cc}$ (Power).** --- ## 3. Functionality and Usage ### How it Works Unlike a passive crystal (which requires external capacitors and an inverter), the K1150BACM-R is an **active oscillator**. When 5V is applied across the $V_{cc}$ and Ground pins, it immediately begins outputting a square wave at its fixed frequency on the Output pin. ### Common Applications * **Microprocessor Clocks:** Providing the "heartbeat" for older or industrial CPUs. * **Ethernet Controllers:** Timing for data packet transmission. * **Embedded Systems:** Reliable timing in harsh environments due to the metal casing. * **Legacy Hardware Maintenance:** Often found in telecommunications rack equipment. --- ## 4. Deciphering the Part Number * **K1150:** The series identifier (Standard 5V Crystal Oscillator). * **BACM:** Internal manufacturer codes for stability, temperature range (usually 0°C to 70°C), and duty cycle (40/60%). * **-R:** Denotes **RoHS Compliance**, meaning the part is manufactured without lead or other hazardous substances. ---
