Figure 3–20. XCVR Section in the Early Power Estimator
Pre-Emphasis Setting Second
Post-Tap Enter the pre-emphasis second post-tap setting used by the transmitter.
VOD Setting Enter the output differential voltage (VOD) setting of the GXB Transmitter
channel PMA. It is assumed that the transmitter uses a termination
resistance of 100
Ω.
ADCE Enter whether or not the Adaptive Dispersion Control Engine (ADCE)
feature is used.
Channel Power (W) This shows the total power of the GXB Transmitter channel PMA and GXB
Receiver channel PMA blocks for all channels (in W). This value is
calculated automatically.
CCU Power (W) This shows the total power of the GXB PLLs and control circuitry for all
channels (in W). This value is calculated automatically.
Total Power (W) This shows the sum of the channel power and CCU power (in W). This
value is calculated automatically.
User Comments Enter any comments. This an optional entry.
