4.10 Recommended Crystal Oscillation Circuit
use of this information.
(1) Connection example
Note: Total loads value of oscillator is sum of external loads (C1 and C2) and floating loads of
TMP91C820A is evaluated by below oscillator vender. When selecting external parts, make
actual assemble board. There is a possibility of miss operating using C1 and C2 value in
below table. When designing board, it should design minimum length pattern around
oscillator. And we recommend that oscillator evaluation try on your actual using board.
