Power
CS5366 features five independent power pins that power various functional blocks within the device and
allow for convenient interfacing to other devices.
each supply pin. Please refer to
each power supply pin. The power supplied to each power pin can be independent of the power supplied to
any other pin.
To meet full performance specifications, the CS5366 requires normal low-noise board layout. The

to a clean supply. VD, which powers the digital filter, may be run from the system logic supply, or it may be
powered from the analog supply via a single-pole decoupling filter.
Decoupling capacitors should be placed as near to the ADC as possible, with the lower value high-frequen-
cy capacitors placed nearest to the device leads. Clocks should be kept away from the FILT+ and VQ pins
in order to avoid unwanted coupling of these signals into the device. The FILT+ and VQ decoupling capac-
itors must be positioned to minimize the electrical path to ground.
The CDB5366 evaluation board demonstrates optimum layout for the device.
Control Port Mode and Stand-Alone Operation
In Stand-Alone Mode, the CS5366 is programmed exclusively with multi-use configuration pins. This mode
provides a set of commonly used features, which comprise a subset of the complete set of device features
offered in Control Port Mode.
To use the CS5366 in Stand-Alone Mode, the configuration pins must be held in a stable state, at valid logic
levels, and RST must be asserted until the power supplies and clocks are stable and valid. More informa-
tion on the reset function is available in
In Control Port Mode, all features of the CS5366 are available. Four multi-use configuration pins become
software pins that support the I²C or SPI bus protocol. To initiate Control Port Mode, a controller that sup-
ports I²C or SPI must be used to enable the internal register functionality. This is done by setting the CP-
EN bit (Bit 7 of the Global Control Port Register). Once CP-EN is set, all of the device configuration pins
are ignored, and the internal register settings determine the operating modes of the part.
