  Hello,

 

The HMC733LC4B data sheet absolute max. spec table shows that the Vtune has a range of -1.0 to +25V, but it doesn't show that it has a power sequence or that it's refered to the VCC. If a voltage is applied to VTUNE when there is no connection at VCC, will the part be damaged? Will the VTUNE voltage appear at VCC (for example, because of an ESD protection structure)? Will the part latch up / not work properly when powered is applied with VTUNE applied first?

 

Best Regards.
