... V AG pin. The common mode range of the TI+ and TI– pins is from 1 minus 2 V. This is an FET gate input. Connecting the TI+ pin will place this am- MOTOROLA plifier’s output (TG) into a high–impedance state, thus allow- ing the TG pin to serve as a high–impedance input to the transmit filter. TI– ...

... MOTOROLA The DT output will remain in a high–impedance state for at least two FST pulses after power–up. MASTER CLOCK Since this codec–filter design has a single DAC architec- ture, the MCLK pin is used as the master clock for all analog signal processing including analog–to–digital conversion, digital– ...

... This device was designed for ease of implementation, but due to the large dynamic range and the noisy nature of the environment for this device (digital switches, radio tele- phones, DSP front–end, etc.) special care must be taken to assure optimum analog transmission performance. MOTOROLA ...

... These methods will result in the lowest resistance and the lowest inductance in the ground circuit. This is important to reduce voltage spikes in the ground circuit MOTOROLA resulting from the high speed digital current spikes. The magnitude of digitally induced voltage spikes may be hundreds of times larger than the analog signal the device is required to digitize ...
