The **K1100BACSEM-R** is a specific part number for a **Crystal Clock Oscillator**, typically manufactured by Microchip (formerly Microsemi/Vectron). It belongs to the K1100 series, which is known for its reliability in legacy and industrial timing applications. --- ## 1. Technical Specifications The following table outlines the primary electronic characteristics of this component: | Parameter | Specification | | :--- | :--- | | **Component Type** | Crystal Clock Oscillator (XO) | | **Output Type** | CMOS / TTL Compatible | | **Frequency Range** | Typically fixed (refer to specific datasheet for exact MHz) | | **Supply Voltage ($V_{cc}$)** | 5.0V (Standard for K1100 Series) | | **Package / Case** | 14-pin DIP (Dual In-line Package) - 4 pins used | | **Operating Temperature** | -40°C to +85°C (Industrial Grade) | | **Stability** | ±50ppm or ±100ppm (Suffix dependent) | | **Mounting Type** | Through-Hole | --- ## 2. Part Number Breakdown (Nomenclature) The suffix codes indicate specific features of the oscillator: * **K1100**: The base series (5V, Through-hole). * **B**: Often denotes specific frequency stability or temperature range (check manufacturer specific revision). * **AC**: Indicates the output logic type (typically CMOS/TTL). * **SEM**: Often refers to specialized testing or custom electrical parameters requested by a client (Special Electrical Modification). * **R**: Generally stands for **RoHS Compliant** (Lead-free). --- ## 3. Pin Configuration Although it uses a 14-pin DIP footprint, only four pins are active. The standard layout for this series is: | Pin Number | Function | Description | | :--- | :--- | :--- | | **Pin 1** | NC / Tri-state | No Connection or Output Enable/Disable | | **Pin 7** | GND | Ground | | **Pin 8** | Output | The generated clock signal | | **Pin 14** | $V_{cc}$ | Positive Power Supply (+5V) | --- ## 4. Key Electronic Features * **Hermetically Sealed:** The unit is encased in a metal "can" package to protect the quartz crystal from environmental humidity and interference. * **Low Phase Jitter:** Designed for stable timing in synchronous digital circuits. * **Legacy Compatibility:** These oscillators are frequently used as drop-in replacements for older 8-bit and 16-bit microprocessor systems (e.g., Z80, 6502, or 8051 based boards). ---
