The Timing Description of CODEC Function

TIMING

DESCRIPTION

tA, ta VDD / AVDD ¡ Ü3.0VDC

tC MCLK started

tC ⇒ tG MCLK keeps

tc ⇒ tg

tG, tg Power-down started ( MCLK keeps High or Low )

tJ, tl Power-down ended ( MCLK started )

tF ⇒ t I MCLK keeps High or Low

tA ⇒ tB the charge time of VBG ( where VBG bypass cap. = 0.1uF )

ta ⇒ tb

tC ⇒ tD the charge time of internal clock detector circuit

tJ ⇒ tK

tc ⇒ td

tk ⇒ tl

tD ⇒ tE the lock-in time of PLL ( C1=100pF, C2=6pF, R1=68KΩ )

tK ⇒ tL

td ⇒ te

tl ⇒ tm

tD ⇒ tF the charge time of VAG ( where VAG bypass cap. = 0.1uF )

tK ⇒ tM

td ⇒ tf

tG ⇒ tH the discharge time of internal clock detector circuit

tg ⇒ th

tH ⇒ tI the discharge time of VAG ( where VAG bypass cap. = 0.1uF )

th ⇒ tj

th ⇒ ti the delay time of VBG disable ( where VBG bypass cap. = 0.1uF )

tl ⇒ tn the re-charge time of VBG ( where VBG bypass cap. = 0.1uF )

the re-charge time of VAG ( where VAG bypass cap. = 0.1uF )

@ when change VBG bypass capacitor (C15) :

i. from 0.1uF to 1uF : (tA ⇒ tB)’ ¡ Ü10 ∗ (tA ⇒ tB)

ii. from 0.1uF to 0.01uF : (tA ⇒ tB)’ ¡ Ü1/10 ∗ (tA ⇒ tB)
