Hello,
what are the specs of the TBCLK-input and what are it's requirements?
My application has 12x LDC1000, therefore it would be easier & cheaper to use only one external oscillator, instead of 12x crystal.
But to dimension / choose the proper external oscillator, Cin or load data from TBCLK-input should be known (data is missing in datasheet). Can you please give me that figures, both for 3.3V and 5V?
Is it admissible to form a "daisy chain", connecting XOUT from one LDC1000 to the TBCLK-input of the next one?
How important is the symmetry (duty cycle) of the external clock? Depending on type (and price) duty cycle specs varie i.e. between 40%/60% to 45%/55% or 50%/50%.
Thanks & regards,
Gerardo
