TA2063F 2002-10-30 5 application circuit (cautions) quality of crystal oscillation waveform largely effects s / n ratio. further, this is also true when system clock is input externally through the xi terminal of pin( 1 2). suppress glitch of input signals (lrck, bck, data) as could as possible. the wiring between the tc9268 / 76 / 78 output and the analogue filter amplifier input must be made the shortest. the capacitor between v da and gnda shall be connected as close to the pin as possible.
