Note 1: Analog tuning input sensitivity is 0V to 5V into 5 k Ω , 2.5V for no pull.
2: Analog tuning is disabled by default. Digital tuning is recommended instead.
3: Shall be connected to GND externally.
4: 10 MHz, CMOS square wave, VL < 0.3V, VH > 3V. Amplitude is dependent on load.
5: Signal and Supply. It is recommended to tie this ground to same node as baseplate
ground Pin 2.
6: BITE output (active-low):
0 = Normal Operation
1 = Unlock Condition
7: If connecting to COM port of a computer, a TTL/RS-232 (or HCMOS/RS-232)
adapter is necessary.
