PURPOSE: An apparatus for acquiring a broadcast transport channel interleaving synchronization in an IMT(International Mobile Telecommunication)-2000 terminal and a method therefor are provided to efficiently acquire the 20msec synchronization of a broadcast transport channel without a broadcast transport channel interleaving signal. CONSTITUTION: A secondary deinterleaving result storing unit(105) stores broadcast transport channel data which are secondarily deinterleaved by a 10ms unit. If data corresponding to 30ms are stored in the secondary deinterleaving result storing unit(105), a primary deinterleaver unit(107) primarily interleaves data with a length of 20ms, centering around a certain time, among the stored data according to a timing control signal. A CRC(Cyclic Redundancy Check) unit(111) performs the CRC of the primarily deinterleaved data. A timing control unit(113) generates the timing control signal, and provides the timing control signal to the primary deinterleaver unit(107). If an error exists as a result of the CRC of the CRC unit(111), the timing control unit(113) delays the generation of the timing control signal by 10ms from the certain time, and generates the timing control signal.
