Demo Circuit 192A: LT1684 Ring Signal Generator Quick Start Guide
Quick start guide for the DC192A demo circuit, showcasing the LT1684 for telephone ring signal generation with cadenced and continuous modes via a PIC16C73 microcontroller.
Overview
The DC192A is a demonstration circuit designed to evaluate the LT1684 ring signal generator. It utilizes a Microchip PIC16C73 microcontroller to manage ring signals, cadence, zero-crossing detection, and relay outputs. The board operates from a single 5V supply and supports various modes, including a standard 20Hz 3 REN cadenced ring. Users can configure the board via jumpers for high or low output current capacity (up to 10 REN), softstart, undervoltage lockout, and PWM source selection. Output connections include a standard phone jack or test points for Tip and Ring signals.
Use Cases
- Telephone ring signal generation
- Evaluating the LT1684 ringer controller
