Description
The Realtek RTL2070L is a 6 mm square chip (QFN) with 12 pins per side. It operates at a voltage of 3.3 Volts and is equipped with a 28.8 MHz crystal. This IC chip is specifically 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 "L" in the model name represents the USB (2.0) interface, which allows for easy connectivity. The chip features four pins for USB interface: +Voltage, D-, D+, and ground. It is recommended to use a USB extension cord with RTL-SDR to minimize interference from computer generated noise. Additionally, the RTL2070L includes eight general purpose input/output ports and an infrared remote control port.
