XR2211P

The XR2211P is designed as one kind of FSK demodulator or tone decoder with some features such as:(1)excellent Temp. stability,+50ppm/°C,max.;(2)adjustable tracking range,+1% to 80%;(3)wide dynamic range,10mV to 3V rms;(4)FSK demodulation,with carrier detection;(5)HCMOS/TTL/Logic compatibility;(6)wide supply voltage range,4.5V to 20V;(7)wide frequency range,0.01Hz to 300kHz.It can be used in caller identification delivery,FSK demodulation,Data synchronization,tone decoding and FM detection,carrier detection.

The XR2211P is a monolithic phase-locked loop (PLL) system especially designed for data communications applications.It is particularly suited for FSK modem
applications.It operates over a wide supply voltage range of 4.5 to 20V and a wide frequency range of 0.01Hz to 300kHz.It can accommodate analog signals between 10mV and 3V,and can interface with conventional DTL,TTL,and ECL logic families.The circuit consists of a basic PLL for tracking an input signal within the pass band,a quadrature phase detector which provides carrier detection,and an FSK voltage comparator which provides FSK demodulation.

The absolute maximum ratings of the XR2211P can be summarized as:(1)power supply:20V;(2)input signal level:3V rms;(3)power dissipation:900mW;(4)package power dissipation ratings(CDIP):750mW,derate above TA=25°C:8mW/°C;(5)package power dissipation ratings(PDIP):800mW,derate above TA=25°C:60mW/°C;(6)package power dissipation ratings(SOIC):390 mW;(7)derate above TA=25°C:5mW/°C.If you want to know more information such as the electrical characteristics about the XR2211P,please download the datasheet in www.seekdatasheet.com .
