make sure the oscillator is fully stable). In
normal start-up conditions, this power on
reset circuit should reset the chip when power
is applied. If your application could
experience abnormal power start-up
conditions, it is recommended that the serial
port reinitialization sequence, followed by a
power save command, be performed to
guarantee that the converter begins proper
operation.
2.12 PCB Layout
The CS5541 should be placed entirely over an ana-
log ground plane with the DGND pin of the device
connected to the analog ground plane. Place the an-
alog-digital plane split immediately adjacent to the
digital portion of the chip
See the CDB5540/41 data sheet for suggested lay-
out details and Applications Note 18 for more de-
tailed layout guidelines.
