CLOCK RECOVERY CIRCUIT

摘要

A clock regeneration circuit which is formed as an integrated circuit except for a SAW (surface acoustic wave) filter module which can be used unaltered for a number of regeneration circuits which are provided for various clock frequencies and the design of the SAW filter modules for such regeneration circuits are designed such that the SAW filter modules have an increasing phase for decreasing clock frequency. An in-phase data rate generation is possible even though the integrated circuit always supplies the filter module with pulses of identical lengths for all clock frequencies and an improved clock regeneration circuit results.
