RESISTOR Rt
0 ohms Ideal, 2.2 ohms max
4.7 ohms Ideal
0 ohms
NOTES:
1. Resistor values are +/-1%.
2. The Rt resistors are used to protect the device from over–voltage.
3. See the Separate Application Note for details on how to construct a protected interface.
4. Normally a TTL level clock is applied MCLK and the XTAL pin is left as an NC. Optionally a crystal can be applied across
the MCLK and XTALD pins.
