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 GO1555/GO1525*. This pin is an output.
Should be isolated from all other power supplies.
*For new designs use GO1555
Ground reference for the external voltage controlled oscillator. Connect to
pins 2, 4, 6, and 8 of the GO1555/GO1525*. This pin is an output.
Should be isolated from all other grounds.
*For new designs use GO1555
Differential inputs for the external VCO reference signal. For single ended
devices such as the GO1555/GO1525*, VCO should be AC coupled to
VCO_GND.
VCO is nominally 1.485GHz.
*For new designs use GO1555
No Connect.
