Input for an external +2.500 V voltage reference relative to VREF-.
This pin should be tied to VA- near the voltage reference output.
A CMOS compatible clock input for the modulator internal master clock, nominally 2.048 MHz
with an amplitude equal to the VD digital power supply.
A low to high transition resets the internal clock phasing of the modulator. This assures the
sampling instant and modulator data output are synchronous to the external system.
_
When high, adds approximately -60 mV or -35 mV of internal differential offset to the analog
input signal to guarantee any ΔΣ idle tones are removed. When low, no offset is added.
When high, the modulator is in power-down mode. Halting MCLK while in power down mode
reduces modulator power dissipation further.
Modulator data is output as a 1-bit serial data stream at 512 kHz with an MCLK input of
2.048 MHz.
A high level output indicates the modulator is unstable due to an over-range on the analog
inputs.
