Abstract: A bit rate converter capable of avoiding slip of data in a memory for use in bit rate adjustment is disclosed. A phase comparator compares a write address and a read address of the memory to produce a phase difference. The write address is ahead of the read address in the memory. A stuffing rate controller selects one of a plurality of preset fixed stuffing rates depending on the phase difference. A stuff pulse inserter inserts a stuff pulse into readout data from the memory at the selected stuffing rate. When normally operating, a normal fixed stuffing rate is selected. When the phase difference is small than a lowest threshold value, a higher fixed stuffing rate is selected. When the phase difference is greater than a highest threshold value, a lower fixed stuffing rate is selected.
