Notes:
1. Si5345 test configuration: 10x 3.3 V LVDS outputs enabled @156.25 MHz. Excludes power in termination resistors.
2. Si5344 test configuration: 4x 3.3 V LVDS outputs enabled @ 156.25 MHz. Excludes power in termination resistors.
3. Si5342 test configuration: 2x 3.3 V LVDS outputs enabled @ 156.25 MHz. Excludes power in termination resistors.
4. Differential outputs terminated into an AC coupled 100  load.
5. LVCMOS outputs measured into a 6 inch 50  PCB trace with 5 pF load. Measurements were made in CMOS3 mode.
6. Detailed power consumption for any configuration can be estimated using ClockBuilder Pro when an evaluation board
(EVB) is not available. All EVBs support detailed current measurements for any configuration.
