Abstract: PURPOSE:To attain proper response to both hit and steady-state error modes by providing an alarm raising condition circuit and two alarm restoration condition circuits different from each other in code error rate to attain processing. CONSTITUTION:If (n) code errors or more in inputted error pulses exist in a prescribed time the alarm raising condition circuit 1 gives an output, causing an FF circuit 3 to raise an alarm. Let the restoring conditions of the 1st and 2nd alarm restoring condition circuits 4, 5 be those that no code error exists during times tau4 and tau5 (tau5>tau4) respectively. An output of the circuit 5 is ANDed with an output of the circuit 4 at an AND circuit 7 via a delay circuit 6 in a delay time tau3. In case of the momentary interruption mode (1), an output of the alarm circuit restores normally in the time tau4 after the line is restored during the time tau3 after entering the alarming state. In case of the mode (2) where the code error rate deteriorating time is the tau3 or over, since the restoration to the normal state of the alarm circuit output depends on the conditions of the circuit 5, the probability causing chattering where the alarming and its release are repeated is suppressed lower.

Filed: 1997-02-19
Abstract: PROBLEM TO BE SOLVED: To obtain the phase locked loop PLL circuit of which a reference leakage is reduced and a lockup time speed is increased. SOLUTION: In the PLL circuit where a charge pump current is selected, a pulse width generator 27 identifies a difference of pulse width between an up-pulse signal S22a and a down-pulse signal 22b to control an output current of a charge pump circuit 23, and in the case that the PLL circuit is not locked and the pulse width is large, an output current of the charge pump circuit 23 is increased to quicken change in charges given to a loop filter 24. In the case that the PLL circuit is locked and the difference of the pulse width is small, the output current of the charge pump circuit 23 is decreased. Thus, the lockup time of the PLL circuit is decreased and the effect of an external disturbance on the loop filter is reduced and a reference leakage is reduced.

Abstract: PURPOSE:To simultaneously execute electric characteristic tests which are to be performed respectively before a fuse is blown and after the fuse has been blown by a method wherein the supply of a power-supply voltage is controlled so as to be shut off with reference to a fuse corresponding to a redundant cell. CONSTITUTION:When fuses F1 to Fn are blown actually in conventional cases, the supply of a power-supply voltage to a CMOS inverter in each redundant fuse circuit is stopped, and outputs OUT1 to OUTn in individual redundant fuse circuits are set to an H level. In this execution example, a piece of input data PC which includes a piece of information on a blown redundant fuse is set to a shift register SR for redundant-cell selection use, and the supply or the shutoff of a power-supply voltage to individual redundant fuses F1 to Fn is controlled. In this case, the supply of the power-supply voltage to the fuse corresponding to the redundant cell is shut off, and a state which is equivalent to the shutoff can be produced without actually blowing the fuse. Thereby, the output of a redundant fuse circuit can be set to an H level.
