Using a 0.47 µF capacitor in series with the primary of a transformer recommended in the Applications section. 12. Pulse amplitude measured at the output of a 1:1 or 1:1.26 transformer across a 75 Ω load for line length setting LEN2/1/0 = 0/0/0. 13. Pulse amplitude measured at the output of a 1:1.26 transformer across a 120 Ω load for line length setting LEN2/1/0 = 0/0/0. 14. Pulse amplitude measured at the output of a 1:1.15 transformer across a 100 Ω load for line length setting LEN2/1/0 = 0/1/0. 15. Pulse amplitude measured at the DSX-1 cross-connect across a 100 Ω load for line length settings LEN2/1/0 = 0/1/1, 1/0/0, 1/0/1, 1/1/0, or 1/1/1 using a 1:1.15 transformer and the length of #22 AWG, ABAM, or equivalent cable specified in Table 3. 16. Input signal to RTIP/RRING is jitter free. Values will reduce slightly if jitter free clock is input to TCLK. 17. Not production tested. Parameters guaranteed by design and characterization. 18. Return loss = 20 log10 ABS((z1 +z0)/(z1-z0)) where z1 = impedance of the transmitter, and z0 = impedance of line load. Measured with a repeating 1010 data pattern with LEN2/1/0 = 0/0/0 and a 1:1 transformer terminated with a 75 Ω load, or a 1:1.26 transformer terminated with a 120 Ω load. 19. Measured broadband through a 0.5 Ω resistor across the secondary of a 1:1.26 transformer during the transmission of an all ones data pattern for LEN2/1/0 = 0/0/0. CS61574A CS61575 DS154F2 3 |
