SLOS416C – JUNE 2003 – REVISED JUNE 2009 PRINTED CIRCUIT BOARD LAYOUT TECHNIQUES FOR OPTIMAL PERFORMANCE Achieving optimum performance with high frequency amplifier-like devices in the THS3201 requires careful attention to board layout parasitic and external component types.

THS3201 SLOS416C – JUNE 2003 – REVISED JUNE 2009 ............................................................................................................................................................. www.ti.com • Socketing a high-speed part like the THS3201 is not recommended. The additional lead length and pin-to-pin capacitance introduced by the socket can create an extremely troublesome parasitic network which can make it almost impossible to achieve a smooth, stable frequency response.
