Description and Introduction

Video-Signal Conditioners with AGC and Back-Porch Clamp The MAX7452ESA+ is a single-channel, monochrome on-screen display (OSD) generator from Maxim Integrated. Below are its specifications, descriptions, and features:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Package:** 8-SOIC (150mil)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Supply Voltage:** 4.5V to 5.5V  
- **Current Consumption:** 10mA (typical)  
- **Resolution:** Up to 12 rows × 30 columns (character-based)  
- **Character Memory:** 256 user-programmable characters  
- **Character Size:** Configurable (8x12, 8x13, or 8x14 pixels)  
- **Sync Inputs:** Supports composite, S-video, or RGB video signals  
- **Video Input/Output:** NTSC or PAL compatible  

### **Descriptions:**  
The MAX7452ESA+ is designed for superimposing text and graphics onto video signals in real time. It includes an integrated EEPROM for storing user-defined characters and supports both NTSC and PAL video standards. The device is commonly used in security cameras, automotive displays, and consumer electronics for displaying status information or menus.

### **Features:**  
- **Integrated EEPROM:** Stores 256 user-programmable characters.  
- **Automatic Video Sync Detection:** Works with composite, S-video, or RGB inputs.  
- **Flexible Character Configuration:** Adjustable character size and positioning.  
- **Low Power Consumption:** Typically 10mA operating current.  
- **Wide Operating Voltage:** 4.5V to 5.5V supply range.  
- **On-Chip LDO Regulator:** Simplifies power supply design.  
- **Serial Interface:** SPI-compatible for easy microcontroller communication.  
- **RoHS Compliant:** Lead-free and environmentally friendly.

Alternative Part Number

  • LMH0302SQ/NOPB --: 3G/HD/SD SDI cable driver with similar equalization and cable-driver function, widely available and pin-compatible in function.
  • GS2972-IBE3 --: Integrated SDI cable driver/equalizer supporting SD/HD/3G rates, a common cross for MAX7452 SDI cable-driver applications.
  • LMH0384SQ/NOPB --: SDI adaptive cable equalizer with comparable performance and supply, suitable as a functional replacement in SDI receive paths.
  • LMH0302SQE/NOPB --: 3G/HD/SD SDI cable driver with similar equalization and output drive functions, commonly used as a cross-reference for MAX7452-class SDI cable drivers.
  • GS2978-CNE3 --: SDI cable driver/equalizer IC covering SD/HD/3G data rates, functionally comparable to the MAX7452 in video transmission applications.
  • LMH0384SQE/NOPB --: Adaptive cable equalizer with SDI support, suitable alternative when the equalizer function of the MAX7452 is the key requirement.
