詳細說明
The CXA2075 is a high-performance bipolar monolithic FM IF system IC designed for use in FM/AM/FM-IF digital tuner applications. It features a wide dynamic range that allows for improved signal quality and performance. The CXA2075 also includes an IF amplifier, a quadrature detector, an RSSI circuit, and an oscillator circuit in a single chip.The IF amplifier in the CXA2075 provides 73 dB of gain with a bandwidth of 180 kHz to 25 MHz, offering excellent sensitivity and selectivity for FM reception. The quadrature detector utilizes a double-balanced mixer to provide accurate demodulation of the FM signal. The RSSI circuit allows for signal strength measurement, which can be used for automatic gain control in the tuner circuit.The CXA2075 operates on a single 4.5V to 12V power supply and is housed in a compact 16-pin SOP package, making it suitable for small form factor tuner designs.
