NAME NO. TYPE(1) DESCRIPTION
DIFFERENTIAL/SINGLE-ENDED CLOCK INPUT
IN0_P 9 I Primary: Differential input pair or single-ended input
IN0_N 10
IN1_P 5 I Secondary: Differential input pair or single-ended input.

Note that INP0, INN0 are used indistinguishably with IN0_P, IN0_N.

IN1_N 6
INPUT SELECT
IN_SEL 2 I Input Selection with an internal 500-kΩ pullup and 320-kΩ pulldown, selects input port. See Table 9-1.
