Note 1: At TA = -40°C, DC characteristics are guaranteed by design and characterization.

Note 2: CML outputs open.

Note 3: RL = 50Ω to VCC.

Note 4: AC characteristics are guaranteed by design and characterization.

Note 5: Relative to the falling edge of SCLKO+. See Figure 2.

Note 6: Measured with 223 - 1 PRBS.

Note 7: Jitter BW = 12kHz to 20MHz.
