(the rc is connected between osc terminal and vss.) figure 4. oscillation frequency is about 38khz 5khz at r = 38k w and c = 1000pf. r up r up code1 code2 initialize rup = 20k w c = 0.001 m f - 0.022 m f csc schmitt fosc r c r = 39k w 5% c = 1000pf 5%
infraed remocon receiver s5g9801x01/s5g9803x01 7 3. receiving signal input circuit signal received by the light receiving element is sent through the pre-amp to the detector, when a 38 khz carrier wave is eliminated and the signal enters a remin pin of the receiving signal input circuit. the receiving signal input circuit (remin) has a built-in schmitt trigger for shaping receiving signal waveforms to eliminate rounding. figure 5. 4. receiving signal check the receiving signal check is to check the 2-cycle transmitting signal sent from the transmitter to check whether it is a normal signal or not. figure 6. the first data is stored in the 12-bit data register. then, when the second data is entered, the previous data is pushed out from the data register one by one. the pushed out data and incoming data are checked to see if they are same. if any errors are caused during the 12-bit receiving data check, the system is reset at that time. and when all receiv- ing data are same, output is raised from l level to h level. the status of receiving data, register clock and check pulse are shown below. register clock is provided in the data center by taking frequency margins of the transmitter and the receiver into consideration. amp det remin ph302b 12 bits second data first data 12 bits
