Description ■ ■ ■ This Terrestrial NIM(Network Interface Module) is designed for using in DVB-T system. It builts in COFDM-Demod IC. It's used to a single conversion approach with the reception frequency range in VHF C5 ∼ C12 (174MHz ∼ 230MHz), UHF C21 ∼ C69 (470MHz ∼ 862MHz) Band selection and tuning is done by PLL IC. PLL IC is controlled by the COFDM-Demod IC.(external control port pins) ■ 2.
