TM100 Description

The TM100 is a fully integrated programmable thermal management unit that monitors, controls, and corrects analog circuitry across a wide temperature range. The TM100 is primarily intended for TCXO applications and includes a temperature sensor, internal Pierce oscillator & output stage and data converters in conjunction with a microcontroller (MCU) and memory structures to run a temperature correction programs. The integrated Pierce oscillator and output stage are designed to be flexible with a variety of oscillator and crystal configurations. The IC includes many programmable functionality options. The TM100 has an accompanying software package that makes it easy to configure and to enter coefficients for up to a 7th order crystal correction algorithm. It communicates via an I2C interface and is available in an 3mm x 3mm package or as die.
