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 combined with a microcontroller (MCU) and memory structures to run temperature correction programs. The integrated Pierce oscillator and output stage are designed to be flexible with a variety of oscillator and crystal configurations. The TM100 includes many programmable functionality options, and a software package makes it easy to configure and implement customizable crystal correction algorithms. It communicates via an I2C interface and is available in a 3mm x 3mm package or as die.
