How to Apply 1.8-V Signals to 3.3-V CDCLVC11xx Fanout Clock Buffer
Texas InstrumentsThe CDCLVC11xx buffer family from Texas Instruments has a nominal voltage supply of 2.5 V and 3.3 V. With the simple employment of an external RC network this family of devices can handle incoming signals whose voltage levels go up to 1.8 V. This application report explains how to implement this network and dimension its discrete components without impacting the specifications of additive ji
HC5503PRC SLIC and the Texas Instruments TP3057A Combined PCM Codec and Filter
Texas InstrumentsThe network requirements of many countries require the analog subscriber line circuit (SLIC) to terminate the subscriber line with an impedance for voiceband frequencies which is complex rather than resistive (e.g. 600 Ohms). This requires that the physical resistance that is situated between the SLIC and the subscriber line comprised of protection and/or sensing resistors and the output resist
