19 17 CLKSET
Clock Set Input. Setting CLKSET to Logic high (connect CLKSET to VREG) sets the CLKOUT to 2× the
internal oscillator frequency and is in phase with the oscillator. Setting CLKSET to Logic low sets the
CLKOUT to 1× the oscillator frequency and 180° out of phase.
20 18 CLKOUT
Clock Output. The CLKOUT frequency, f
CLKOUT
, is either 1× or 2× the oscillator frequency. CLKOUT can
0be used to synchronize another ADP1828 or ADP1829 controllers. Set f
CLKOUT
to 1× when synchronizing
another ADP1828, or to 2× when synchronizing the ADP1829. If SYNC is used, f
SYNC
= f
CLKOUT
independent of the CLKSET voltage. CLKOUT is able to drive a 100 pF load.
