13 / 159 page  13/159 ¡ Semiconductor MSM6688/6688L AC Characteristics Items with * are proportional to the period of master clock frequency fosc. Items with ** are proportional to the period of the master clock frequency fosc, and are also proportional to the sampling frequency fSAMP during record/playback. Note: 1. The oscillation start stabilization time is added to tREX and tBPD. The oscillation start stabilization time is several tens of milliseconds for crystals and several hundreds of microseconds for ceramic oscillators. Note: 2. The oscillation start stabilization time is added if PDMD pin = "L". The oscillation start stabilization time is several tens of milliseconds for crystals and several hundreds of microseconds for ceramic oscillators. DVDD=DVDD'=AVDD=4.5 to 5.5V DGND=AGND=0V Ta=–40 to +85°C fosc=4.096MHz fSAMP=8.0kHz Parameter Symbol Min. Typ. Max.
