NOTES
1See AD6600 Timing Diagrams.
2All switching specifications tested by driving ENC and
ENC differentially.
3Several timing specifications are a function of Encode high time, t
ENCH; these specifications are shown in the data tables and timing diagrams. Encode duty cycle
should be kept as close to 50% as possible.
4Encode pulse low directly affects the amount of settling time available at FLT resonant port. See External Analog (Resonant) Filter section for details.
5The 2
× Clock is generated internally, therefore some specifications are functions of encode period and duty cycle. All timing measurements to or from CLK2 × are
referenced to 2.0 V crossing.
6This specification IS a function of Encode period and duty cycle; reference timing diagrams Figure 8.
7Output rise time is measured from 20% point to 80% point of total CLK2
× voltage swing; output fall time is measured from 80% point to 20% point of total CLK2×
voltage swing.
8Output rise time is measured from 20% point to 80% point of total data voltage swing; output fall time is measured from 80% point to 20% point of total data voltage
swing. All outputs specified with 10 pF load.
Specifications subject to change without notice.
