Notes: 7. Using a 0.47 µF capacitor in series with the primary of a transformer recommended in the Applications

Section.

8. Pulse amplitude measured at the output of the transformer across a 75

. load for line length settings

LEN[2:0] = 001 and 000.

9. Pulse amplitude measured at the output of the transformer across a 120

. load for line length setting

LEN[2:0] = 000.

10. Pulse amplitude measured at the output of the transformer across a 100

. load for line length setting

LEN[2:0] = 000.

11. Pulse amplitude measured at the DSX-1 Cross-Connect for all line length settings from LEN[2:0] = 011

to LEN[2:0] = 111.

12. Assuming that jitter free clock is input to TCLK. Jitter Attenuator not in path.

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

14. Measured broadband through a 0.5

. resistor across the secondary of the transmitter transformer

during the transmission of an all ones data pattern with LEN[2:0] = 000 or 001.
