TRANSMITTER OUTPUT JITTER
The transmit jitter specification ensures compliance with ITU-T G.823 and G.825 and ANSI T1.105.03-1994 for
all supported rates. The corner frequency of the transmit PLL is nominally 3.0 MHz.

TRANSMITTER SPECIFICATIONS FOR CMI INTERFACE IN E4 MODE
Bit Rate: 139.264Mbit/s
±
15ppm
Code: coded mark inversion (CMI)
The following specifications are met with the external components for E4 operation, above, and configured with
a recommended 1:1 transformer as in Figure 10. With the coaxial output port driving a 75
load, the output
pulses conform to the templates in Figure 4 and Figure 5.
