°C to 85°C; TV+, RV+ = 5.0 V ±5%; GND = 0 V)

Notes: 8. Using a 0.47 µF capacitor in series with the primary of a transformer recommended in the Applications

Section.

9. Pulse amplitude measured at the secondary of the transformer across a 75

Ω load.

10. Pulse amplitude measured at the secondary of the transformer across a 120

Ω load.

11. Assuming that jitter free clock is input to TCLK.

12. Not production tested. Parameters guaranteed by design and characterization.

13. Measured broadband through a 0.5

Ω resistor across the secondary of the transmitter transformer

during the transmission of an all ones data pattern.

14. Data decision threshold established after the receiver equalizer filters pulse overshoot and undershoot.

15. Jitter tolerance for 0 dB input signal level. Jitter tolerance increases at lower frequencies.
