Notes:

1. The typical normal mode (or low power mode) LVDS maximum is 100 mV (or 80 mV) higher than the TIA/EIA-644

maximum. For normal and low-power modes, the amplitudes are programmable through register settings and can be

stored in NVM. Each output driver can be programmed independently. See Appendix A of the Si5341/40 Reference

Manual.

2. Driver output impedance depends on selected output mode (Normal, Low Power).

3. Measured for 156.25 MHz carrier frequency. Sinewave noise added to VDDO (1.8 V = 50 mVpp, 2.5 V/

3.3 V = 100 mVpp) and noise spur amplitude measured.

4. Measured across two adjacent outputs, both in LVDS mode, with the victim running at 155.52 MHz and the aggressor

at 156.25 MHz. Refer to application note, “AN862: Optimizing Si534x Jitter Performance in Next Generation Internet

Infrastructure Systems”, guidance on crosstalk minimization.

5. For other amplitudes see Appendix A of the Si5341/40 Reference Manual.

6. See Note 4, but in this case the measurement is across two output clocks that have a single clock between them.

7. Same as Note 4, but the Si5340 has less crosstalk due to the spacing of adjacent outputs.
