- DJAT Jitter Transfer E1 Modes
Frequency Range
In the non-attenuating mode for T1 rates, that is, when the FIFO is within one UI
of overrunning or under running, the tracking range is 1.48 to 1.608 MHz. The
guaranteed linear operating range for the jittered input clock is 1.544 MHz ± 200
Hz with worst case jitter (29 UIpp) and maximum XCLK frequency offset (± 100
ppm). The nominal range is 1.544 MHz ± 963 Hz with no jitter or XCLK
frequency offset.
In the non-attenuating mode for E1 rates the tracking range is 1.963 to 2.133
MHz. The guaranteed linear operating range for the jittered input clock is 2.048
MHz ± 1278 Hz with worst case jitter (42 UIpp) and maximum XCLK frequency
offset (± 100 ppm).
9.6 Timing Options (TOPS)
The Timing Options block provides a means of selecting the source of the
internal input clock to the TJAT block, the reference clock for the TJAT digital
PLL, and the clock source used to derive the transmit clock to the M13 mux or
SONET/SDH mapper.
