The **ADCMP604BKSZ-R2** is a high-performance, very fast comparator manufactured by Analog Devices. It is specifically designed for high-speed applications where timing precision and low jitter are critical. --- ### 1. Key Technical Specifications Below are the primary electrical characteristics of the ADCMP604BKSZ-R2: | Parameter | Specification | | :--- | :--- | | **Propagation Delay** | 1.6 ns (Typical) | | **Logic Type** | LVDS (Low Voltage Differential Signaling) | | **Supply Voltage (Single)** | 2.5 V to 5.5 V | | **Supply Current** | 21 mA (Typical) | | **Input Common-Mode Range** | -0.2 V to Vcc + 0.2 V | | **Packaging** | SC70-6 (Small Outline Transistor) | | **Operating Temperature** | -40°C to +125°C | --- ### 2. Functional Features The device incorporates several advanced features that make it suitable for modern high-speed signal chains: * **LVDS Output:** The output stage provides a standard LVDS signal, which is highly resistant to electromagnetic interference (EMI) and allows for high-speed data transmission over differential traces. * **Rail-to-Rail Inputs:** The input stage can handle voltages slightly beyond the power supply rails, preventing phase reversal and ensuring stability. * **Internal Hysteresis:** It includes internal hysteresis to prevent multiple transitions (chattering) caused by noise on the input signal. * **Shutdown Pin:** It features a power-down mode to conserve energy in battery-operated or thermal-sensitive applications. --- ### 3. Pin Configuration (SC70-6) The device is housed in a tiny 6-lead package. The typical pinout is as follows: | Pin No. | Name | Description | | :--- | :--- | :--- | | 1 | **Q** | Non-inverting LVDS Output | | 2 | **Vee** | Negative Supply (Ground) | | 3 | **Vp** | Non-inverting Input | | 4 | **Vn** | Inverting Input | | 5 | **Vcc** | Positive Supply | | 6 | **QN** | Inverting LVDS Output | --- ### 4. Typical Applications Due to its 1.6 ns propagation delay and LVDS output, the ADCMP604 is commonly found in: 1. **High-speed Line Receivers:** Converting analog signals into digital differential streams. 2. **Clock and Data Restoration:** Cleaning up jittery timing signals. 3. **Threshold Detectors:** Fast pulse detection in LiDAR or medical imaging. 4. **FPGA Interfacing:** Directly driving high-speed FPGA input pins without level shifters. --- ### 5.
