Frequency of BCLK (may vary from 64KHz to 4.096MHz in 8KHz
increments, TS5070 only)
Period of BCLK High (measured from V
Period of BCLK Low (measured from V
Rise Time of BCLK (measured from V
Fall Time of BCLK (measured from V
Hold Time, BCLK Low to FS
Setup Time FS
Delay Time, BCLK High to Data Valid (load = 100pF plus 2 LSTTL
loads)
Delay Time from BCLK8 Low to Dx Disabled (if FSx already low);
FSx Low to Dx Disabled (if BCLK8 low);
BCLK9 High to Dx Disabled (if FSx still high)
Delay Time from BCLK and FSx Both High to TSx Low (Load = 100pF
plus 2 LSTTL loads)
Delay Time from BCLK8 low to TSx Disabled (if FSx already low);
FSx Low to TSx Disabled
BCLK9 High to TSx Disabled
Delay Time, FSx High to Data Valid (load = 100pF plus 2 LSTTL
loads, applies if FSx rises later than BCLK rising edge in non-
delayed data mode only)
