TCM129C18 General Description
The TCM29C18, TCM29C19, TCM129C18, and TCM129C19 are low-cost single-chip PCM codecs (pulse-code-modulated encoders and decoders) and PCM line filters. These devices incorporate both the A/D and D/A functions, an antialiasing filter (A/D), and a smoothing filter (D/A). They are ideal for use with the TMS320 DSP family members, particularly those featuring a serial port such as the TMS32020, TMS32011,and TMS320C25.
Primary applications include:
• Digital encryption systems
• Digital voice-band data storage systems
• Digital signal processing
These devices are designed to perform encoding of analog input signals (A/D conversion) and decoding of digital PCM signals (D/A conversion). They are useful for implementation in the analog interface of a digital signal processing system. Both devices also provide band-pass filtering of the analog signals prior to encoding,and smoothing after decoding.
The TCM29C18 and TCM29C19 are characterized for operation over the temperature range of 0 to 70.
The TCM129C18 and TCM129C19 are characterized for operation over the temperature range of 40 to 85.

† Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTE 1: Voltage values for maximum ratings are with respect to VBB.
