Description

The CXA3038N is an IC for IQ-detection of DSS, DVB, and other digital satellite broadcast QPSK modulation signals in the 480 MHz band. It consists of an AGC amplifier circuit, oscillator circuit, phase shifter circuit, and phase comparison circuit. In addition, the chip CXA3038N has a PLL circuit for frequency control and built-in control data. It realizes highaccuracy oscillator frequencies through use of a lowcost LC resonance circuit.
