Output Clock 1.
Differential output clock with a frequency range of 2 kHz to 1.4 GHz.
Output signal format is selected by SFOUT1_REG register bits. Out-
put is differential for LVPECL, LVDS, and CML compatible modes.
For CMOS format, both output pins drive identical single-ended
clock outputs.
Output Clock 2.
Differential output clock with a frequency range of 2 kHz to 1.4 GHz.
Output signal format is selected by SFOUT2_REG register bits. Out-
put is differential for LVPECL, LVDS, and CML compatible modes.
For CMOS format, both output pins drive identical single-ended
clock outputs.
Control Mode.
Selects I
0 = I
1 = SPI Control Mode
This pin must not be NC. Tie either high or low.
See the Si53xx Family Reference Manual for details on I
operation.
Ground Pad.
The ground pad must provide a low thermal and electrical
impedance to a ground plane.
