PowerPlay Early Power Estimator Inputs
There are six transceiver power rails: V
CCT
, V
CCH
, V
CCR
, V
CCA
, V
CCP,
and
V
CCL
.
Table 3–10
describes the information reported for each rail.
Each row in the XCVR section represents a separate transceiver domain.
For each transceiver domain used, you need to enter the number of
channels, the mode of the transceiver, the data rate (in Mbps), the width
of the parallel data bus, the Pre-Emphasis setting, and the VOD setting.
For certain modes, you must specify whether the byte serializer, rate
match FIFO setting, and 8B10B encoder are used.
Table 3–11
describes the values that need to be entered in the XCVR
section of the PowerPlay Early Power Estimator.
Table 3–10. Transceiver Power Supply Information in the I/O Section
Column Heading
Description
Power Rails
Power supply rails for the transceiver blocks.
Voltage (V)
The voltage applied to the specified power rail in Volts (V).
Current (A)
The current drawn from the specified power rail in Amps (A).
This includes power drawn by transceivers in user modes and unused transceivers in
power-down mode.

Column Heading
Description
Module
Enter a name for the module in this column. This is an optional value.
# of Channels Used
Enter the number of channels used in this transceiver domain. The
channels are grouped together in one QUAD or two adjacent QUADs and
clocked by a common PLL. The number of channels allowed in each
domain depends on mode:
PCI-Express: One to three channels for PIPEx1, four channels for PIPEx4
or eight channels for PIPEx8
XAUI: Four channels only
Other modes: One to four channels.
Mode
Enter the communication protocol or standard these transceivers
implement. Options include Basic 3G, Basic 6G, (OIF) CEI PHY Interface,
GIGE, PCI Express (PIPE), Scrambled 5G, SONET Backplane OC12,
SONET Backplane OC48, SONET Backplane OC96 and XAUI.
Data Rate (Mbps)
Enter the data rate the transceivers will operate at (in Mbps). In Basic
mode this number must be specified:
●
Basic 3G is 622 to 3125 Mbps
●
Basic 6G is 3126 to 6375 Mbps
For other modes the data rate is fixed.
