The **2262D-R6** typically refers to a specific variation of a remote control transmitter/encoder module or integrated circuit, most commonly based on the **PT2262** architecture. These are widely used in wireless communication systems operating at 315MHz or 433MHz. Below is a breakdown of the electronic components and technical specifications associated with this part. --- ### 1. Core Component: The PT2262 Encoder IC The heart of the 2262D-R6 is the **PT2262** (or a compatible CMOS encoder). It converts parallel data inputs into a serial bit stream for RF transmission. | Feature | Specification | | :--- | :--- | | **Operating Voltage** | 4V to 15V (DC) | | **Encoding Type** | Tri-state (0, 1, Open) | | **Address Codes** | Up to 531,441 combinations ($3^{12}$) | | **Modulation** | ASK (Amplitude Shift Keying) | | **Package** | Usually SOP-20 or DIP-18 | --- ### 2. Peripheral Electronic Parts To make the 2262D-R6 functional, several passive and active components are integrated onto the PCB: #### A. Timing Resistor ($R_{osc}$) * **Function:** Controls the internal oscillator frequency. * **Importance:** This must match the decoder's resistor (e.g., PT2272). For example, if the transmitter uses 4.7MΩ, the receiver must be tuned accordingly to "understand" the signal pulse width. #### B. SAW Resonator (Surface Acoustic Wave) * **Function:** Stabilizes the RF carrier frequency (usually 315MHz or 433.92MHz). * **Part Note:** This looks like a small metal "can" (TO-39 or SMD package) on the board. #### C. Addressing Pins (Jumpers/Pads) * **Function:** Allows the user to set a unique security code. * **Structure:** 8 to 12 pins that can be soldered to High (VCC), Low (GND), or left Floating. #### D. Transistor/RF Amplifier * **Function:** Boosts the signal from the IC before it reaches the antenna. * **Common Part:** Small NPN transistors (like the 2SC3356). --- ### 3. Pin Configuration (Common 2262 Series) If you are looking at the IC or the module pins, here is the standard layout: | Pin Name | Description | | :--- | :--- | | **A0 - A5** | Address bits (used for security coding). | | **A6/D5 - A11/D0** | Dual-purpose Address or Data bits. | | **VCC / VSS** | Power supply (Positive / Ground). | | **TE** | Transmission Enable (Active Low). | | **OSC1 / OSC2** | Connections for the Oscillator Resistor. | | **DOUT** | Serial Data Output to the RF stage. | --- ### 4. Typical Applications * **Garage Door Openers:** Secure wireless entry. * **Wireless Security Systems:** PIR sensors or door magnets. * **Remote Switches:** Controlling lights or fans wirelessly. * **Industrial Paging:** Simple "On/Off" remote signaling. ---
