Figure C-3. Interface Signals of the Source Module Connector
The codes indicated on the illustration above translate as follows:
MOD DO
Source module data line zero. Signals MOD DO
through MOD D3 are the mm source module
data bus lines (bi-directional).
MOD Dl
Data line one.
MOD D2
Data line two.
MOD D3
Data line three.
MOD CO
Source module control line zero. Signals MOD
CO and MOD Cl are the control lines for the
read/write to and from the mm source module.
MOD Cl
Control line one.
CLAMP CNTL
Source module clamp control (not used).
MOD SENSE
Source module sense. A 1mA current is injected
on this line by the mm source module to
indicate its presence. This signal always equals
o v .
L MOD RF OFF
Low = RF off. Source module RF is turned off.
EXT LVL RET
Source module external leveling return.
EXT LVL
Source module external leveling input, from the
mm source module.
Internal 0.5V/GHz to the mm source module.
Power supply. Range is -14.25 to -15.9OV.
Power supply. Range is +14.25 to +16.4OV
Power supply. Range is i-7.75 to +8.25V.
Power supply. Range is t4.75 to t5.45V.
DIG GND
Digital ground.
MOD ANLG GND
Source module analog ground.
ANLG GND RET
Analog ground return.
