6. Conversion time scales directly to the master clock speed. The times shown are for synchronous, internal loopback

(FRN) mode) with 8.0 MHz CLKIN. In PDT, RBT, and SSC modes, asynchronous delay between the falling edge

of

master clock cycles + 10 ns. In PDT, RBT, and SSC modes, CLKIN can be increased as long as the

rate is 100 kHz max.

7. The CS5101A requires 6 clock cycles of coarse charge, followed by a minimum of 1.125

µs of fine charge. FRN

mode allows 9 cycles for fine charge which provides for the minimum 1.125

µs with an 8MHz clock, however; in

PDT, RBT, or SSC modes and at clock frequencies of 8 MHz or less, fine charge may be less than 9 clock cycles.

This reflects the typical specification (6 clock cycles + 1.125

µs).

8. Throughput is the sum of the acquisition and conversion times. It will vary in accordance with conditions affecting

acquisition and conversion times, as described above.

9. All outputs unloaded. All inputs at VD+ or DGND.

10. Power consumption in the sleep mode applies with no master clock applied (CLKIN held high or low).

11. With 300 mV p-p, 1-kHz ripple applied to each supply separately in the bipolar mode. Rejection improves by 6 dB

in the unipolar mode to 90 dB. Figure 25 shows a plot of typical power supply rejection versus frequency.
