Description
Clock input / output. By selecting coupling
capacitors (C3 / C4) this port may be used to
monitor the on-board 19.2MHz reference or the
external reference input.
Input to receiver LNA.
By selecting components this port may be used
as an LNA output or input to the receiver mixer.
Coupling capacitor C168 can be fitted to use the
off-chip 1^st mixer (U15). In this mode T3 should
be removed.
NB: This port is a test port designed to allow
connection of a coax cable.
1^st Mixer Output or input to IF filter (F2).
Output of IF filter (F2) or input to CMX990
receiver IF stages.
EV9900 is not configured to use this port.
EV9900 is not configured to use this port.
Monitor point for Tx VCO feedback signal.
900MHz transmitter output.
Input or output / monitor for main local oscillator.
Input or output / monitor for auxiliary (180MHz)
local oscillator (normally not connected).
7.2V power supply input.
3.5V power supply for RF power amplifier.
Power supply ground.
8 bit parallel interface from CMX990 to host /
controller or PC. See schematics and CMX990
datasheet for details.
EV9900 is not configured to use this port.
EV9900 is not configured to use these pins.
DAC3 output.
DAC2 output.
ADC5 input.
ADC4 input.
400MHz Transmitter Output (not used in default
EV9900 configuration).
EV9900 is not configured to use this connector.
TX / RX Switch Output (Default configuration of
EV9900 does not use this connector).
