IPC: H03M3/02
Filed: 1989-06-14
Abstract: PURPOSE:To switch an analog part and a digital part and to conduct the best tests of them efficiently by providing a switch means and leading a quantized data sequence out of a chip, and inputting external test data to a digital filter. CONSTITUTION:An input analog signal which is passed through a prepositioned filter is sampled wtih a 1st sampling signal of frequency much higher than the frequency of a conversion signal and quantized by a quantizing circuit. Then the quantized sequence is passed through the switch means and the digital filter of the digital part and thinned out with a 2nd sampling signal for thinning whose frequency is lower than that of the 1st sampling signal to become the output digital signal of the oversampling A/D converter. When this switch means is switched with an external signal, the quantized data sequence is led out of the chip and test data which is inputted from outside is applied to the digital filter. Therefore, the analog part and digital part are easily switched and the best tests can be conducted efficiency without increasing the circuit scale.

Title: Synchronizing circuit
Inventor: SAITO KAZUAKI
IPC: H03L7/06
Filed: 1987-06-19
Abstract: PURPOSE:To prevent erroneous pull-in due to an echo from being performed and to heighten the stability of holding phase synchronization, by supplying reception data to a differentiation circuit through an echo inhibit circuit which removes the echo generated on a transmission line from the reception data when reference phase information is taken out from the reception data in a time divisional transmitter. CONSTITUTION:The echo inhibit circuit 20 is provided at the reception data input part of the differentiating circuit 16 which generates the differential pulse of the reception data to be phase-compared with an extraction clock. The pull-in time of the synchronizing circuit is decided by the input of a synchronous state display signal which represents step out to the echo inhibit circuit 20. An echo inhibit operation is started by the supplying of the signal, and when one differential pulse generated at the differentiating circuit is inputted, the echo inhibit circuit closes a gate so as not to input the reception data to the differentiating circuit. Next, the extraction clock supplied to the input part is counted, and the echo inhibit operation is canceled when a count value arrives at a prescribed number and no influence of the echo is given, then, the gate is opened, and the reception data passes and is supplied to the differentiating circuit.
