Description
Control voltage to external voltage controlled oscillator. Nominally +1.25V
DC.
Power supply for the external voltage controlled oscillator. Connect to pin 7
of the GO1525. This pin is an output.
Should be isolated from all other power supplies.
Ground reference for the external voltage controlled oscillator. Connect to
pins 2, 4, 6, and 8 of the GO1525. This pin is an output.
Should be isolated from all other grounds.
Differential inputs for the external VCO reference signal. For single ended
devices such as the GO1525, VCO should be AC coupled to VCO_GND.
VCO is nominally 1.485GHz.
No Connect.
PARALLEL DATA BUS CLOCK
Signal levels are LVCMOS/LVTTL compatible.
HD 20-bit mode
