(reference value) 1) power on a) all data must be set on ic when the pow er supply is tuned on. (sub add : 00h to 07h) b) if limit amplifier must be on at the time of the initial data transfer of i 2 c. (sub add : 04h, d7 = "1") c) the power supply transition time (v cc1, 2 = 0 9 v) must be more than 10 ms. d) electric current flows in the power supply off condition when a power supply is connected to the tuned terminal (pin 21). therefore, be careful in the case of the backup mode such as a microcomputer. 2) pin 16 don't use pin 16 (zap). it must be open. 3) monitor function a) pin 21 of this ic has a function to monitor internal circuit terminals of this ic. the monitor point of analog si gnal or digital si gnal is set by subadd : 04h, d0 to d3. the choice of monitor point of lo gic signal is subadd : 0ah .it is chosen by d0 to d2 of 0ah. b) don't choose more than one monitor poi nt (analog, logic) at the same time. c) it is prohibited choosing the mon itor point when if limit amplifier is co mpulsory off (subadd : 04h, d7 = "0"). be sure to turn on if limit amplifier when you use monitor function. d) monitor function is a function for the test purpose onl y in our company, and its f unction is not guaranteed. when it is needed to send data, all data must be "0". don't use it with the actual tuner set. 4) charge pump test function a) subadd : 04h d4 to d5 are the bits fo r the function check of charge pump. for a normal use, they must be set to "0". 5) handling unused bits a) all unused bits must be set to "0". wh en it is necessary to input subaddress da ta, all unused bits mu st be set to "0". 6) set number of n divider don't establish n value about settlement of n divider in 271 or less. 7) the timing of if counter if counter starts to count when it detects stop condition of write mode at sds mode (sub add : 01h, d1 = "1"). the result of the if count can get it when it begins to read it after the progress about more than 70 ms and it is made the mode and begins to read it. to prevent if counter?s abnormal function, so that stop c ondition may not come between about 70 ms of the following. (see the figure below.) even if this tim ing isn't kept, ic doesn't become unc ontrollable. but the following condition are occurred by the transmitting data. a) when there are data which turn off sds : counter stops, and it is re set. the judgment result of if coun ter isn't right. ignore data and erase it. b) in the case of the dummy data: stop condition is ignored, and if counter works as it is. (it is n't reset.) if an original access prohibition time passes, the proper result of if counter is obtained.
