General Description

The RTL2832U is a high-performance DVB-T COFDM demodulator that supports a USB 2.0 interface.

The RTL2832U complies with NorDig Unified 1.0.3, D-Book 5.0, and EN300 744 (ETSI Specification).

It supports 2K or 8K mode with 6, 7, and 8MHz bandwidth. Modulation parameters, e.g., code rate, and

guard interval, are automatically detected.

The RTL2832U supports tuners at IF (Intermediate Frequency, 36.125MHz), low-IF (4.57MHz), or

Zero-IF output using a 28.8MHz crystal. Embedded with an advanced ADC (Analog-to-Digital

Converter), the RTL2832U features high stability in portable reception.
