Title: Clock detector
Inventor: FUJINO SHOJI
IPC: G01R29/02
Filed: 1987-06-10
Abstract: PURPOSE:To enable detection on whether a correct clock including changes in duty ratio is supplied or not, by comparing a delayed clock in the phase with an original clock. CONSTITUTION:When a duty ratio of a clock C3 is 50%, the clock C3 is inverted through a clock inversion means 8. Then, the inversion clock -C3 is delayed by a half of a prescribed cycle thereof using a delay means 9 to obtain a delay clock C4. The clocks C3 and C4 are inputted into a coincidence comparison means 10 and when the clock C3 has a prescribed frequency, the delay clock C4 coincides with the clock C3. When the frequency of the clocks C3 deviates or an amplitude level varies, both the clocks C3 and C4 do not coincide. This enables judgment on whether the clock is normal or not from a clock detection signal DET3 from the means 10.
