CXA3038N is IQ Detection IC for Digital Satellite Broadcast Tuner manufactured by Sony Semiconductor Solutions.
IQ Detection IC for Digital Satellite Broadcast Tuner
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 parison circuit. In addition, the chip 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. Features
- Built-in PLL for controlling oscillator frequency.
- Oscillator frequency based at 479.5 MHz is adjustable in ±4 steps of 50 k Hz 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 d B. Applications Digital satellite broadcast tuner Structure Bipolar silicon monolithic IC 24 pin SSOP...
