The TP3054-X, TP3057-X Extended Temperature Serial Interface CODEC/Filter COMBO® Family is a monolithic PCM CODEC/filter from National that can be used to convert analog signals to digital signals or digital signals to analog signals. This product uses National's advanced double-poly CMOS process (microCMOS), which offers wide operating temperature range and high precision.
The TP3054-X and TP3057-X family consists of p-law and A-law monolithic PCM CODEC/filters utilizing an A/D and D/A conversion architecture. These devices are fabricated using National's advanced double-poly CMOS process (microCMOS) and feature a complete CODEC and filtering system including transmit high-pass/low-pass filtering, receive low-pass filter with sin x/x correction, active RC noise filters, and internal precision voltage reference.
The devices operate in a temperature range of -40°C to +85°C.
The devices require two 1.536 MHz, 1.544 MHz or 2.048 MHz transmit and receive master clocks.
The low operating power is typically 50 mW.
