The invention relates to a nuclear magnetic resonance imaging radio frequency receiver, the receiver being adapted to receive analogue signals from at least one radio frequency receiver coil unit (122; 204; 306), the radio frequency receiver comprising an analogue-digital converter (408) to convert the analogue magnetic resonance signal into a first digital signal, a resampling and demodulation unit (414) to convert the first digital signal into a second digital signal, a communication interface (400: 600; 602) adapted for transmitting the second digital signal via a communication link (202), and a first clock generator (406) for generating a sampling clock, the sampling clock being the direct clock source for the analogue-digital converter (408), the first clock generator (406) being adapted to generate the sampling clock using a digital timing reference, the digital timing reference being received digitally via the communication link (202) by the communication interface (400: 600; 602), wherein the receiver further comprises a second clock generator (410) for generating a system clock, the system clock being the direct clock source for the resampling and demodulation unit (414), the second clock generator (410) being adapted to generate the system clock using the sampling clock.
