DEVICE CONFIGURATION CONTROL

Figure 27 illustrates the relationships between device states, the control pins, device initialization and

configuration, and device operational modes. In pin mode, the state of the control pins determines the

configuration of the device for all device states. In programming mode, the device registers are initialized to their

default state and the host can update the configuration by writing to the device registers. A system may transition

a device from pin mode to host connected mode by changing the state of the SI_MODE pins and then triggering

a device reset (either via the RESETN pin or via setting the RESETN bit in the device registers). In reset, the

device disables the outputs so that unwanted sporadic activity associated with device initialization does not

appear on the device outputs.

CONFIGURING THE RESETN PIN

Figure 26 shows two typical applications examples of the RESETN pin.

Figure 26. RESETN/PWR Pin Configurations

Figure 26 (a) SPI / I2C mode only: shows the RESETN pin connected to a digital device that controls device

reset. The resistor and capacitor combination ensure reset is held low even if the CDCM6208 is powered up

before the host controller output signal is valid.

Figure 26(b) SPI / I2C mode only:shows a configuration in which the user wishes to introduce a delay between

the time that the system applies power to the device and the device exiting reset. If the user does not use a

capacitor, then the device effectively ignores the state of the RESETN pin.

Figure 26 (c) Pin mode only: shows a configuration useful if the device is used in Pin Mode. Here device pin

number 44 becomes the PWR input. An external pull down resistor can be used to pull this pin down. If the

resistor is not installed, the pin is internally pulled high.

Figure 27 shows how the different possible device configurations and when the VCO becomes calibrated and the

outputs turn on and off.
