3-Level
Signal Format Select.
Three level inputs that select the output signal format (common mode
voltage and differential swing) for all of the clock outputs except
CKOUT5 (see DBL5).
Bypass mode is not available with CMOS outputs. When VDD = 3.3 V,
for thermal reasons, there are restrictions on the number of LVPECL
and CMOS outputs. See the Si53xx-RM reference manual for details.
These pins have both weak pullups and weak pulldowns and default to
M.
Some designs may require an external resistor voltage divider when
driven by an active device that will tri-state.

CKOUT1–
CKOUT1+
OMULTI
Clock Output 1.
Differential output clock with a frequency specified by FRQSEL and
FRQTBL. Output signal format is selected by SFOUT pins. Output is
differential for LVPECL, LVDS, and CML compatible modes. For CMOS
format, both output pins drive identical single-ended clock outputs.

DBL34
I
LVCMOS
Output 3 and 4 Disable.
Active high input. When active, entire CKOUT3 and CKOUT4 divider
and output buffer path is powered down. CKOUT3 and CKOUT4 out-
puts will be in tristate mode during powerdown.
This pin has a weak pullup.

CKOUT5–
CKOUT5+
OMULTI
Clock Output 5.
Fifth high-speed clock output with a frequency specified by FRQSEL
and FRQTBL. Output signal format is selected by SFOUT pins. Output
is differential for LVPECL, LVDS, and CML compatible modes. For
CMOS format, both output pins drive identical single-ended clock out-
puts.

CKOUT2+
CKOUT2–
OMULTI
Clock Output 2.
Differential output clock with a frequency specified by FRQSEL and
FRQTBL. Output signal format is selected by SFOUT pins. Output is
differential for LVPECL, LVDS, and CML compatible modes. For CMOS
format, both output pins drive identical single-ended clock outputs.
