CONNECTORS
Figure C-3. Interface Signals of the Source Module Connector
The co des indicated on the illustration ab ove translate as follows:
MOD D0
Source mo dule data line zero. Signals MOD D0
through MOD D3 are the mm source mo dule
data bus lines (bi-directional).
MOD D1
Data line one.
MOD D2
Data line two.
MOD D3
Data line three.
MOD C0
Source mo dule control line zero. Signals MOD
C0 and MOD C1 are the control lines for the
read/write to and from the mm source mo dule.
MOD C1
Control line one.
CLAMP CNTL
Source mo dule clamp control (not used).
MOD SENSE
Source mo dule sense. A 1mA current is injected
on this line by the mm source mo dule to
indicate its presence. This signal always equals
0V.
L MOD RF OFF
Low = RF o. Source mo dule RF is turned o.
EXT LVL RET
Source mo dule external leveling return.
EXT LVL
Source mo dule external leveling input, from the
mm source mo dule.
0.5V/GHz
Internal 0.5 V/GHz to the mm source mo dule.
0
15V
Power supply. Range is
0
14.25 to
0
15.90 V.
+15V
Power supply. Range is +14.25 to +16.40 V
+8V
Power supply. Range is +7.75 to +8.25 V.
+5V
Power supply. Range is +4.75 to +5.45 V.
DIG GND
Digital ground.
MOD ANLG GND
Source mo dule analog ground.
ANLG GND RET
Analog ground return.
