Layout, Decoupling and Grounding Rules
THS1230
SLAS291B – OCTOBER 2000 – REVISED MARCH 2004
When clocking output data from THS1230, it is important to observe its timing relation to CLK. The pipeline ADC
delay is 5 clock cycles to which the maximum output propagation delay needs to be added.

Proper grounding and layout of the PCB on which THS1230 is populated is essential to achieve the stated
performance. It is advised to use separate analog and digital ground planes that are spliced underneath the IC.
THS1230 has digital and analog pins on opposite sides of the package to make this easier. Because there is no
connection internally between analog and digital grounds, they have to be joined on the PCB. It is advised to do
this at one point in close proximity to THS1230.
Because of the high sampling rate and switched-capacitor architecture, THS1230 generates transients on the
supply and reference lines. Proper decoupling of these lines is therefore essential. Decoupling is recommended
as shown in the schematic of the THS1230 evaluation module in Figure 22.
