SI21622-C60-GM

Video Processing Overview

The Si21622-C60-GM is a dual digital TV demodulator integrating separate high-performance cores for DVB-T2/T and DVB-C2/C standards into an 8x8 mm QFN-68 package. It supports input clock references from 4 to 30 MHz with typical XTAL frequencies between 16 and 30 MHz. Power supplies operate at 1.2 V (VDD_VCORE) and 3.3 V (VDD_VANA/VDD_VIO). Total power consumption per demodulator ranges from 142 mW to 356 mW depending on the standard and test conditions, with a thermal resistance of 42 °C/W on a 4-layer PCB.
