Ordering Guide Notes:
1. Series termination resistor (R
S
– see Apps Circuits section) is recommended for this configuration.
2. Series termination resistor (R
S
) 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.
