Application Circuit Example (Cautions) /Gb7/G20Quality of crystal oscillation waveform largely effects S / N ratio. Further, this is also true when system clock is input externally through the XI pin of pin(16). /Gb7/G20Suppress glitch of input signals (LRCK, BCK, DATA) as could as possible. /Gb7/G20The wiring between the TC9237BF, TC9237BN output and the analog filter amplifier input must be made the shortest /Gb7/G20The capacitor between V DA and GNDA shall be connected as close to the pin as possible. /Gb7/G20NC pin is used in the open state.
