TDA18219HN/C1,518

Video Processing Overview

The TDA18219HN is a silicon tuner for terrestrial and cable digital TV reception. It supports DVB-T/T2, ISDB-T, DTMB, ATSC, and DVB-C standards. The device delivers a LOW IF signal to a channel demodulator. It operates on a single 3.3 V supply voltage with low power consumption. The RF frequency range covers 42 MHz to 870 MHz. The tuner noise figure is typically 5.0 dB at a 75 Ω source. Phase jitter is 0.7 degrees maximum in the UHF band. Image rejection is typically 63 dB. Input compression point is 124 dBμV. The package is HVQFN40 (SOT618-1).
