Claim:
1. A method comprising: selecting one or more attributes of error information through a programming interface, the one or more attributes including a selectable number of bits of resolution of the error information, the error information indicating a difference between a first frequency and a target frequency; generating an oscillator output signal having the first frequency with a micro electro mechanical system (MEMS) oscillator on a first integrated circuit; determining temperature in a temperature sensor and providing an indication of sensed temperature; determining frequency error in the oscillator output signal due to temperature based on the indication of sensed temperature; determining the error information by combining the frequency error determined based on the indication of sensed temperature and frequency error due to an initial frequency offset of the MEMS oscillator from the target frequency; supplying the oscillator output signal and the error information from two or more output terminals of the first integrated circuit, to a receiving system on a second integrated circuit; determining a frequency translation ratio of the oscillator output signal in the receiving system based on the error information and on desired frequency information; generating a clock signal in a frequency translation circuit in the receiving system based on the oscillator output signal and the frequency translation ratio; and supplying the clock signal to functional circuitry of the receiving system.
