REV. 1.0.1

3.3V HIGH-SPEED (110 MHZ) PROGRAMMABLE SKEW CLOCK BUFFER

9

NOTES:

9.

Test measurement levels for the XRK49911 are TTL levels (1.5V to 1.5V). Test conditions assume signal transition

times of 2 ns or less and output loading as shown in the AC Test Loads and Waveforms unless otherwise

specified.

10.

SKEW is defined as the time between the earliest and the latest output transition among all outputs for which the

same tU delay has been selected when all are loaded with 30pF and terminated with 50Ω to VCC/2.
