Abstract
In one aspect the present invention describes an electronic circuit for transmitting voice packet data over a wireless network with an upstream transmission mode and a downstream transmission mode. The circuit comprises a first phase-lock loop (PLL) for locking a first clock to a time stamp signal, wherein the first clock synchronizes upstream data transmission over the wireless network; and a second PLL for locking a second clock to the time stamp signal, wherein the second clock is used for sampling voice data for downstream voice data transmission over the wireless network.
