SNAS787A November 2019 – February 2020 CDCDB2000
PRODUCTION DATA.
The CDCDB2000 allows two methods to control the state of the output channels: SMBus/OE#, and Side-Band Interface. Only one of the two methods can be active at any time, and the active interface is selected by the state of the SBEN pin. Both methods of output control can assign the state of each output individually.
When in SMBus/OE# control is selected, the OE# pins become active. The OE# pins control the state of the output with the same number. For example, the OE5# pin controls the state of the CK5 output driver. The SMBus registers may enable/disable the output regardless of the OE# pin state if desired.
