Notes:
1. Receiver input has hysteresis.
2. Must pull up. See “Pull-Up and Pull-Down Resistors” on page 39 for recommended termination values.
3. Must pull down. See “Pull-Up and Pull-Down Resistors” on page 39 for recommended termination values.
4. If not used, must pull up.
5. If not used, must pull down.
6. Strapping input during reset; pull up or pull down as required.

Signal Name
Analog Test Bus for manufacturing test.
Differential input for external reference clock.
External reference resistor. Attach a 1.37 kΩ, 1% resistor between
RExt and RExtG to provide the reference for both the bias currents
and the impedance calibration circuitry.
Differential receiver for received serial data.
Note: Input must be DC coupled and biased to 0V common mode.
Differential driver for transmitted serial data.
Note: Output must be AC coupled.
External interrupt requests.
External interrupt requests.
External interrupt requests.
External interrupt requests.
Test clock.
Test data in.
Test data out.
Test mode select.
Test reset. Must be low during power-on reset to initialize the JTAG
controller and for normal operation of the chip.
