MC1455D

MC1455 : MC1455, MC1455B, NCV1455B Timers The MC1455 monolithic timing circuit is a highly stable controller capable of producing accurate time delays or oscillation. Additional terminals are provided for triggering or resetting if desired. In the time delay mode, time is precisely controlled by one external resistor and capacitor. For astable operation as an oscillator, the free−running frequency and the duty cycle are both accurately controlled with two external resistors and one capacitor. The circuit may be triggered and reset on falling waveforms, and the output structure can source or sink up to 200 mA or drive TTL circuits. Features • Direct Replacement for NE555 Timers • Timing from Microse.

MC145532 : An Adaptive Differential PCM (ADPCM) transcoder is used to reduce the data rate required to transmit a PCM encoded voice signal while maintaining the voice fidelity and intelligibility of the PCM signal. The transcoder is used on 64 kbps data streams which represent either voice or voice band data signals that have been digitized by a codec (e.g., MC145557). The transcoder uses a filter to attempt to predict the next PCM input value based on previous PCM input values. The error between the predicted and the true PCM input value is the information that is sent to the other end of the line. Hence the word differential, since the ADPCM data stream is the difference between the true PCM input va.

MC145554 : A codec–filter is used for digitizing and reconstructing the human voice. These devices were developed primarily for the telephone network to facilitate voice switching and transmission. Once the voice is digitized, it may be switched by digital switching methods or transmitted long distance (T1, microwave, satellites, etc.) without degradation. The name codec is an acronym from “COder” (for the A/D used to digitize voice) and “DECoder” (for the D/A used for reconstructing voice). A codec is a single device that does both the A/D and D/A conversions. To digitize intelligible voice requires a signal–to–distortion ratio of about 30 dB over a dynamic range of about 40 dB. This can be accomplish.
