DATA FORMATTING CIRCUIT OF A LOW VOLTAGE DRIVE CIRCUIT DATA COMMUNICATION SYSTEM
摘要:
A low voltage drive circuit (LVDC) includes a drive sense circuit operable to convert analog outbound data into an analog transmit signal and convert analog receive signals into analog inbound data, a transmit digital to analog circuit operable to convert transmit digital data into the analog outbound data, and a receive analog to digital circuit including an analog to digital converter, a digital filtering circuit, and a data formatting module. The data formatting module includes a sample and hold circuit operable to sample and hold an n-bit digital value of filtered digital data from the digital filtering circuit to produce an n-bit sampled digital data value, a digital to digital converter circuit operable to adjust formatting of the n-bit sampled digital data value to produce a formatted digital value, and a data packeting circuit operable to generate a packet of received digital data from a plurality of formatted digital values.
