A system for transmission and recovery of original digital data includes an encoder, a transmitter, a receiver, a decoder, and an analog phase locked loop. The analog phase locked loop supplies a sender's clock to the transmitter and a receiver's clock to the receiver, where the sender's clock frequency is a first integer multiple of the system clock frequency, and the receiver's clock frequency is a second integer multiple of the sender's clock frequency within 0.1% tolerance. In a normal flow situation, data frames are output by the receiver in alternate cycles of the system clock. In an overflow situation, data frames are output by the receiver in consecutive cycles of the system clock. In an underflow situation, data frames are not output by the receiver in consecutive cycles of the system clock.
