A device communicating with a node, includes a communication unit configured to transmit a transmitting data segment to the node, and receive a receiving data segment from the node. The device further includes a phase locked loop (PLL) configured to generate an operating frequency for the communication unit. The device further includes a PLL controller configured to control a hold time and a lock time, of the PLL, that are shared between the node and the device. The device further includes a scheduler configured to schedule the transmitting data segment and the receiving data segment based on the controlled hold time and lock time.
