Abstract: Disclosed are a method and a device for recovering clock data of a tributary signal in SDH, wherein the method includes that: it is to extract valid data of the signal from a time slot of each tributary in a synchronous digital hierarchy SDH frame, and store into a storage space corresponding to a time slot of each tributary in a cache; it is to recover a clock signal and a readout signal for the time slot of each tributary by means of time division multiplexing; when the readout signal for the time slot of any tributary is valid, it is to read out contents of the data from the storage space corresponding to the time slot of the tributary in the cache, and latch into a latch corresponding to the time slot; the device includes: a data extracting module, a clock recovery circuit and a data recovery module.
