1.1. Introduction
TUN-VIPER-TX-CLKP B05c (1x)
TUN-VIPER-TX-DATA0 B04c (1x)
TUN-VIPER-TX-DATA0 B05c (1x)
SRP (Service Reference Protocol) is a software tool that creates a list with all references to signal lines. The list contains
TUN-VIPER-TX-DATA1 B04c (1x)
references to the signals within all schematics of a PWB. It replaces the text references currently printed next to the signal
TUN-VIPER-TX-DATA1 B05c (1x)
names in the schematics. These printed references are created manually and are therefore not guaranteed to be 100%
TUN-VIPER-TX-DATA10 B04c (1x)
correct. In addition, in the current crowded schematics there is often none or very little place for these references.
TUN-VIPER-TX-DATA10 B05c (1x)
Some of the PWB schematics will use SRP while others will still use the manual references. Either there will be an SRP
TUN-VIPER-TX-DATA11 B04c (1x)
reference list for a schematic, or there will be printed references in the schematic.
TUN-VIPER-TX-DATA11 B05c (1x)

TUN-VIPER-TX-DATA13 B04c (1x)
TUN-VIPER-TX-DATA13 B05c (1x)
TUN-VIPER-TX-DATA14 B04c (1x)
There are several different signals available in a schematic:
TUN-VIPER-TX-DATA14 B05c (1x)
TUN-VIPER-TX-DATA15 B04c (1x)
1.2.1. Power Supply Lines
TUN-VIPER-TX-DATA15 B05c (1x)
TUN-VIPER-TX-DATA2 B04c (1x)
TUN-VIPER-TX-DATA2 B05c (1x)
All power supply lines are available in the supply line overview (see chapter 6). In the schematics (see chapter 7) is not
TUN-VIPER-TX-DATA3 B04c (1x)
indicated where supplies are coming from or going to.
TUN-VIPER-TX-DATA3 B05c (1x)
It is however indicated if a supply is incoming (created elsewhere), or outgoing (created or adapted in the current schematic).

TUN-VIPER-TX-DATA7 B05c (1x)
TUN-VIPER-TX-DATA8 B04c (1x)
For normal signals, a schematic reference (e.g. B14b) is placed next to the signals.

1.3. SRP Schematics
TXPNXA+ B04g (1x)
TXPNXB- B04b (1x)
TXPNXB- B04g (1x)
SRP is a tool, which automatically creates a list with signal references, indicating on which schematic the signals are used.
TXPNXB+ B04b (1x)
A reference is created for all signals indicated with an SRP symbol, these symbols are:

Bi-directional line (e.g. SDA) into a wire tree.
UP-3V3 B04f (2x)
USB1-DM B05a (2x)
USB1-DP B05a (2x) name
USB-BUS-PW B05a (3x)
Signal line into a wire tree, its direction depends on the circuit (e.g. ingoing for PDP, outgoing for LCD sets).
USB-OVERCUR B05a (3x)
U-VOLT-DETECT B08a (3x)
Remarks:
V_SYNC_IN B03a (1x)
VDISP B04g (2x) • When there is a black dot on the "signal direction arrow" it is an SRP symbol, so there will be a reference to the signal
VN B08a (4x) name in the SRP list.
VP B08a (4x)
• All references to normal grounds (Ground symbols without additional text) are not listed in the reference list, this to keep
VREF-AUD B03b (1x)
it concise.
VREF-AUD B03e (1x)
• Signals that are not used in multiple schematics, but only once or several times in the same schematic, are included
VREF-AUD-POS B03b (2x)
in the SRP reference list, but only with one reference.
VREF-AUD-POS B04a (28x)
VREF-DDRPNX B04d (3x)
Additional Tip:
VREFD-VPRDDR B05b (2x)
VREF-PNX B04c (2x) When using the PDF service manual file, you can very easily search for signal names and follow the signal over all the
VREF-PNX B05c (1x) schematics. In Adobe PDF reader:
VREF-VPRDDR B05b (2x)
• Select the signal name you want to search for, with the "Select text" tool.
V-SYNC-VGA B07b (1x)
• Copy and paste the signal name in the "Search PDF" tool.
Y B07b (2x)
• Search for all occurrences of the signal name.
Y B07c (1x)
• Now you can quickly jump between the different occurrences and follow the signal over all schematics. It is advised to
Y1 B07b (2x)
"zoom in" to e.g. 150% to see clearly, which text is selected. Then you can zoom out, to get an overview of the complete
Y1 B07c (1x)
schematic.
PS. It is recommended to use at least Adobe PDF (reader) version 6.x, due to better search possibilities in this version.
