DS Series Encoder/Decoder Module Data Guide
The Linx DS Series Encoder/Decoder Module is designed for remote control applications. It can operate as either an encoder or a decoder, selected by the E/D_SEL pin. As an encoder, it encodes 8 data bits and 10 address bits for transmission via RF or infrared. As a decoder, it compares received address bits with local settings and outputs matching data bits.
The module operates from 2.2 to 5.5 VDC with low supply current (250 µA at 3V encoder, 400 µA at 3V decoder) and ultra-low standby current of 0.3 µA. It supports two protocols: Holtek-compatible and a serial protocol with faster response. The DS Series comes in a small SMD package with 28 pins and includes a valid transmission indicator.
