3.8 OSCin INPUT
In addition to LVDS and LVPECL inputs, OSCin can also be
driven with a sine wave. The OSCin input can be driven sin-
gle-ended or differentially with sine waves. The configurations
for these are shown in
shows the recommended power level for sine wave operation
for both differential and single-ended sources over frequency.
The part will operate at power levels below the recommended
power level, but as power decreases the PLL noise perfor-
mance will degrade. The VCO noise performance will remain
constant. At the recommended power level the PLL phase
noise degradation from full power operation (8 dBm) is less
than 2 dB.
3.9 MORE THAN EIGHT OUTPUTS WITH AN LMK03000
FAMILY DEVICE
The LMK03000 family devices include eight or less outputs.
When more than 8 outputs are required the footprint compat-
ible LMK01000 family may be used for clock distribution. By

using an LMK03000 device with eight LMK01000 family de-
vices up to 64 clocks may be distributed in many different
LVDS / LVPECL combinations. It's possible to distribute more
than 64 clocks by adding more LMK01000 family devices.
Refer to AN-1864 for more details on how to do this.
