oscillators and mixer, a 30-V output tuning
amplifier, and four NPN band switch drivers. It is
NC – No internal connection
available in a small package outline. The 15-bit
programmable counter and reference divider is controlled by I2C bus protocol. Tuning step frequency is
selectable by this reference-divider ratio for a 4-MHz crystal oscillator.
