Communications device with direct cellular-to-collocated device communication channel interface

A communications device, comprising:

• a cellular communications module including a memory and a processor;
• a Global Navigation Satellite System (GNSS) module;
• a cellular radio frequency (RF) integrated circuit (RFIC) module coupled to the cellular communication module and the GNSS module;
• and
• a communication channel interface that couples the cellular communications module and the GNSS module,
• wherein the cellular RFIC module and the GNSS module are monolithically integrated in a single chip, the single chip comprising:
• clock circuitry configured to:
• receive a clock signal and a temperature sensor signal from a crystal oscillator module,
• utilize the temperature sensor signal as an index for a lookup table to retrieve a frequency correction,
• apply the frequency correction to the clock signal to generate a temperature compensated clock signal, and
• provide the temperature compensated clock signal to the cellular RFIC module and the GNSS module.
