m61528fp rev.1.1, dec.17.2003, page 15 of 30 soft-changing this ic built in the soft-changing circuit for reduce the step-noise of fader when internal switch changing. by this function, switching noise of no-signal and some signals can be reduced. ? soft-changing 1 this is the circuit which changes gain smoothly at the setup time. this function can work as follows, (1) at the time of soft-changing on. (2) slot15/d6=0 (3) after the last soft-changing is completed. for example, the movement when fader is changed from 0db to ?6db is shown in the right figure(ex.1). after this ic receive the data of fader:-6db , this circuit changes fader setting from 0db to ?6db at a time. switching time is the time when it was set up with soft-changing time. (ex. 1) fader : 0db -6db changing. soft-changing time : 33ms fader 0db fader -6db t:soft-changing time (you may change it with serial data.) t=33ms * 1 ) while soft-changing works (pin15 output ?h?) , next data isn't accepted. * 2 ) pin15 outputs ?l?exc ept for the time of sof t-changing. 15 pin output while soft-changing works , pin15 output ? data clock slot13 the latch condition d0 to d14 d15 soft-changing time time d0 d1 d2 83ms(41.5ms) 1 1 1/0 66ms(33ms) 1 0 1/0 41ms(20.5ms) 0 1 1/0 33ms(16.5ms) 0 0 1/0 the change of the soft-changing time is possible by the setting of d2. ? d2=?1? : the left time of the left table.

m61528fp rev.1.1, dec.17.2003, page 16 of 30 ? soft-changing 2 this is the circuit which changes gain by 2db step. this function can work as follows, (1) at the time of soft-changing on. (2) slot15/d6=1 (3) after the last soft-changing is completed. for example, the movement when fader is changed from 0db to ?6dbis shown in the right figure(ex.2). after this ic receive the data of fader:-6db, ?g 0db ? ? ?g -2db ? ? ?g -4db ? ? ?g -6db ? this circuit changes fader setting from 0db to ?6db by 2db step. switching time is the time when it was set up with soft-changing time. total changing time is as the follows. ?? total changing time=soft-changing time the number of the step in the case of the right figure, total changing time is 99ms. (33ms 3 steps) when soft-changing time is long, step noise is more reduced. because the step noise is has relations with soft- changing time. we recommend soft-changing 2. however, please confirm step noise by listening test, and judge it. (ex. 2) fader : 0db -6db changing. soft-changing time : 33ms fader 0db fader -6db t:soft-changing time (you may change it with serial data.) t=33ms * 1 ) while soft-changing works (pin15 output ?h?) , next data isn't accepted. * 2 ) pin15 outputs ?l?exc ept for the time of sof t-changing. 15 pin output while soft-changing works , pin15 output ? data clock slot13 the latch condition d0 to d14 d15
