Applications Information
Wire Bonding
For best performance, gold ball-bonding techniques are recommended. To minimize inductance, keep wire
bond lengths short.
PCB Layout Guidelines
Use high frequency PCB layout techniques with solid ground planes to minimize crosstalk and EMI. Keep
high speed traces as short as possible for signal integrity. Short input and output traces will provide best perfor-
mance.
