A microcontroller software connection is made when the SYNC_MC signal output is created by the micro-
controller on command from the system telemetry. The microcontroller can use an internal counter to re-
time the SYNC_MC signal output to the digital filter SYNC input as required.

The I
signals passing through the transceivers are actively buffered, full I
cannot be used (i.e. high-impedance NACK).
The I

bypass the I
When CDB5376 is used in a distributed measurement network, each node must have a unique address.
This address is used to transmit individual configuration commands and tag the source of returned con-
version data. Address assignment can be either dynamic or static, depending how the telemetry system
is to be implemented.
Dynamic address assignment uses daisy-chained I
surement node. Once a node receives an address, it enables the I
so it can be assigned an address.
Static address assignment has a serial number assigned to each node during manufacturing. When
placed in the network, the location is recorded and a master list of serial numbers vs. location is main-
tained. Alternately, a location-dependent serial number can be assigned during installation.
