  • Description

    The TL2844BD is an electronic component used for AC DC converters and offline switchers. It is a 6 mm square chip with 12 pins per side. The chip uses 3.3 Volts and a 28.8 MHz crystal. It is designed as a DVB-T COFDM Demodulator, where DVB-T stands for Digital Video Broadcasting: Terrestrial and COFDM stands for Coded Orthogonal Frequency-Division Multiplexing. The TL2844BD also features a USB (2.0) interface with 4 pins: +Voltage, D-, D+, and ground. It is recommended to use a USB extension cord to reduce computer generated noise. Additionally, the TL2844BD has eight general purpose input/output ports and an infrared remote control port.
