4.3.1 On-Chip Crystal Oscillator Driver
4.3.2 Externally Generated Master Clock
Master Clock Source
The CS5368 requires a Master Clock that can come from one of two sources: an on-chip crystal oscillator
driver or an externally generated clock.
When using the on-board crystal oscillator driver, the XTI pin (pin 21) is the input for the Master Clock
(MCLK) to the device. The XTO pin (pin 22) must not be used to drive anything other than the oscillator
tank circuitry. When using the on-board crystal driver, the topology shown in
crystal oscillator manufacturer supplies recommended capacitor values. A buffered copy of the XTI input is
available as an output on the MCLK pin (pin 23), which is level-controlled by VLS and may be used to syn-
chronize other parts to the device.
If an external clock is used, the XTI and XTO pins must be grounded, and the MCLK pin becomes an input
for the system master clock. The incoming MCLK should be at the logic level set by the user on the VLS
supply pin.
