Abstract
Apparatus and methods for oscillator interface circuits with quadrature clock generation and phase correction are disclosed. In certain embodiments, a clock system includes an external oscillator that provides a differential input clock signal, and a semiconductor die that includes a first pin that receives a non-inverted component of the differential input clock signal and a second pin that receives an inverted component of the differential input clock signal. The semiconductor die further includes an oscillator interface circuit that includes a first controllable resistor and a first controllable capacitor connected in series between the first pin and the second pin, and a second controllable resistor and a second controllable capacitor connected in series between the second pin and the first pin.
