This pin can have one of the following functions depending on the
part number:
CLKIN (for Si5338A/B/C and Si5338N/P/Q devices only)
Provides a high-impedance clock input for single ended clock
signals. This input should be dc-coupled as shown in “3.2. Input
Stage”, Figure 3.
If this pin is not used, it should be connected to ground.
PINC (for Si5338D/E/F devices only)
Used as the phase increment pin. See "3.10.2. Output Phase
Increment/Decrement" on page 25 for more details. Minimum
pulse width of 100 ns is required for proper operation. If this pin is
not used, it should be connected to ground.
FINC (for Si5338G/H/J devices only)
Used as the frequency increment pin. See "3.10.1. Frequency
Increment/Decrement" on page 25 for more details. Minimum
pulse width of 100 ns is required for proper operation. If this pin is
not used, it should be connected to ground.
OEB (for Si5338K/L/M devices only)
Used as an output enable pin. 0 = All outputs enabled; 1 = All
outputs disabled. By default, outputs are tri-stated when disabled.
This pin can have one of the following functions depending on the
part number
I
This is the LSB of the Si5338 I
70h (111 0000), 1 = I
FDBK (for Si5338N/P/Q devices only)
Provides a high-impedance feedback input for single-ended clock
signals. This input should be dc-coupled as shown in “3.2. Input
Stage”, Figure 3. If this pin is not used, it should be connected to
ground.
PDEC (for Si5338D/E/F) devices only)
Used as the phase decrement pin. See “3.10.2. Output Phase
Increment/Decrement” for more details. Minimum pulse width of
100 ns is required for proper operation. If this pin is not used, it
should be connected to ground.
FDEC (for Si5338G/H/J devices only)
Used as the frequency decrement pin. See “3.10.1. Frequency
Increment/Decrement” for more details. Minimum pulse width of
100 ns is required for proper operation. If this pin is not used, it
should be connected to ground.
