Note:
1. Si5341 test configuration: 7 x 2.5 V LVDS outputs enabled @ 156.25 MHz. Excludes power in termination resistors.
2. Si5340 test configuration: 4 x 2.5 V LVDS outputs enabled @ 156.25 MHz. Excludes power in termination resistors.
3. Differential outputs terminated into an ac-coupled 100 Ω load.
4. LVCMOS outputs measured into a 6-inch 50 W PCB trace with 5 pF load. The LVCMOS outputs were set to
OUTx_CMOS_DRV=3, which is the strongest driver setting. Refer to the Si5341/40 Family Reference Manual for more details on
register settings.

5. Detailed power consumption for any configuration can be estimated using ClockBuilderPro when an evaluation board (EVB) is not
available. All EVBs support detailed current measurements for any configuration.
