RC2211A

The RC2211A has the following features including Wide frequency range-0.01 Hz to 300 kHz;Wide supply voltage range-4.5V l0 20V;DTL/TTL/ECL logic compatibility;FSK demodulation with carrier-detector;Wide dynamic range-2 mV to 3 VRMS.

The RC2211A is a monolithic phase-locked loop (PLL) system especially designed for data communications. It is particularly wcll-suitcd for FSK modcm applications, and operates over a wide frequency range of 0.01 Hz l0 300 kHz.It can accommodate analog signals between 2 mV 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 frequency within the passband, a quadrature phase detector which provides carrier detection, and an FSK voltage comparator which provides FSK demodulation. External components are used to independently set carrier frequency, bandwidth and output delay.This is the high impedance output of the quadrature phase detector, and is internally connected to the input of lock detector voltage comparator. In tone detection applications,pin 3 is connected to ground through a parallel combination of RD and CD (see Figure 1) to eliminate chatter at the lock detector outputs. If this tone detector section is not used,pin 3 can be left open circuited.

Life support devices or systems are devices or systems which, (a) are intended for surgical implant into the body,or (b) support or sustain life, and (c) whose failure to perform when properly used in accordance with instructions for use provided in the labeling, can be reasonably expected to result in a significant injury of the user.A critical component in any component of a life support device or system whose failure to perform can be reasonably expected to cause the failure of the life support device or system, or to affect its safety or effectiveness.At present there is not too much information about RC2211A.If you are willing to find more  about RC2211A, please pay attention to our web!
