) is not needed for this configuration. Output impedance is 50Ω for the indicated supply condition.
3. Series termination resistor (R
S
) is not needed for this configuration. Reduced EMI setting.
4. 3.2 x 5 mm package is delivered as 3.2 x 4 mm and accommodates the industry-standard 3.2 x 5 mm footprint.
5. Select option to support maximum anticipated frequency needed.

Notes for both FS/OE tables above:
1. If the internal pull-up resistor order option is NOT selected, an MCU internal pull-up resistor or an external pull-up resistor should be used.
See data sheet for more information.
2. The parallel combination of all pull-up resistors on the FS/OE pin including the optional internal pull-up resistor must be > 20 k to select
Weak High.
3. If the Si50x internal pull-up resistor is enabled with no other external OE connections, the OE state will be detected as “Weak High”,
selecting Frequency 2 by default.
