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.
Ground reference for the external voltage controlled oscillator. Connect to
pins 2, 4, 6, and 8 of the GSO1525.
Should be isolated from all other grounds.
Power supply for the external voltage controlled oscillator. Connect to pin
5 of the GO1525.
Should be isolated from all other power supplies.
Control voltage to external voltage controlled oscillator. Nominally +1.25V
DC.
PLL lock time constant capacitor connection. Normally connected to
VCO_GND through 2.2nF.
Control voltage to set the loop bandwidth of the integrated reclocker.
Normally connected to VCO_VCC through 40k Ω .
Ground connection for the charge pump. Connect to analog GND.
