Can the TPS65950 HFCLKIN pin support a clipped sine wave oscillator input? The datasheet mentions using a sine or square wave input, but does not explicitly state a clipped sine wave as an option. The post here: http://e2e.ti.com/support/power_management/pmu/f/43/p/100613/353167.aspx#353167 seems to indicate it should work.
Thanks
