Figure 12. External (CMOS Compatible) Clock
Figure 13. Using a Microcontroller as a Clock
output word rate (OWR) for the CS5511/13 is de-
rived from the internal oscillator, and is equal to
f
osc
/612. Due to the part-to-part variances in the
oscillator frequency, the OWR of the CS5511/13
can vary between 53 Sps and 159 Sps.

Performing Conversions
After power and a clock source are established to
the CS5510/11/12/13, the ADCs begin performing
conversions. The three sections that follow explain
how to read conversion data from each ADC, and
decode the conversion word into the respective
flag and data bits. Keep in mind that in the
CS5510/12, SCLK provides the external clock
source for the converter. Data is clocked from the
CS5510/12 at the rate set by the external clock
source (typically 32.768 kHz). The CS5511/13 pro-
vides an on-chip oscillator for the master clock. In
the CS5511/13, SCLK is asynchronous to the on-
chip oscillator and can be clocked at a rate up to
2 MHz.
