Abstract:
1. A telecommunications device, comprising: a first baseband processor in a first clock domain operable at a first clock frequency; a second baseband processor in a second clock domain operable at a second clock frequency; first and second jitter buffer pairs interfacing between said first baseband processor and said second baseband processor domain, said first jitter buffer pair comprising first and second jitter buffers, and said second jitter buffer pair comprising third and fourth jitter buffers at least one of said first and second jitter buffers, and at least one of said third and fourth jitter buffers comprising a voiceband exchange buffer; a counter for counting movement of a buffer pointer; a filter coupled to receive an output of said counter; means for adjusting a number of samples needed to fill a voiceband exchange buffer based on said filter output; wherein said first or second jitter buffers and said third or fourth jitter buffers alternately fill at a rate according to said first clock frequency and empty at a rate according to said second clock frequency, wherein alternation between said first and second jitter buffers and said third and fourth jitter buffers occurs at a rate according to said second clocking frequency.
