Clock extraction circuit for a PCM signal |
摘要 |
A clock extraction circuit for PCM NRZ signals which delivers substantially constant power and comprising at least one energy storage device charged by a constant current and discharged into a full wave amplifying circuit, the amplifying circuit delivering power to a filter which filters out the clock signal. This arrangement uses a passive tank circuit and ensures the clock signal from the NRZ data does not die out during periods of little or no clock content in the data stream.
