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 has a PLL circuit for frequency
control and built-in control data. It realizes high-
accuracy oscillator frequencies through use of a low-
cost LC resonance circuit.
Features
Built-in PLL for controlling oscillator frequency.
Oscillator frequency based at 479.5 MHz is
adjustable in ±4 steps of 50 kHz using the voltage
of the control pin.
Reference OSC allows switching to 4 MHz or 10
MHz.
Built-in output buffer for reference OSC.
Low-impedance IQ output.
AGC gain variation 35 dB.
Applications
Digital satellite broadcast tuner
Structure
Bipolar silicon monolithic IC
