摘要： An application-specific integrated circuit (ASIC) for use with a programmable I/O module includes programmable circuitry that enables the ASIC to be configured to support various different I/O functions. The ASIC includes a pin interface, a data interface, a digital section, and an analog section. The pin interface supports analog and digital signal communication and the data interface supports digital data communication. The digital section includes registers for storing digital data such as configuration commands, signal control commands, and digital signal information. The analog section is in electrical signal communication with pin interface and digital data communication with the registers. The analog section includes multiple function-specific elements for processing an electrical signal that is communicated via the pin interface such that the analog section can be configured to establish one of multiple different function-specific processing paths in response to a configuration command received via the data interface.

摘要： Disclosed are various embodiments of temperature-compensated relaxation oscillator circuits that may be fabricated using conventional CMOS manufacturing techniques. The relaxation oscillator circuits described herein exhibit superior low temperature coefficient performance characteristics, and do not require the use of expensive off-chip high precision resistors to effect temperature compensation. Positive and negative temperature coefficient resistors arranged in a resistor array offset one another to provide temperature compensation in the relaxation oscillator circuit.

摘要： An error detector for a pseudo-random bit sequence (PRBS). A plurality of bits of a PRBS are received in a predictor circuit. A comparator compares two of the bits to predict a next bit in the sequence. The predicted next bit is compared with the actual next bit that is received to determine if there is an error in the actual next bit, and if so, the actual next bit is corrected accordingly. The erroneous actual next bit is replaced with the corrected actual next bit and is then used to predict a future actual next bit. A trigger circuit delays correction during initial operation until the predictor contains a bit sequence in which no errors have been detected.
