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.
