Detailed Description

LTC6945: Ultralow Noise and Spurious 0.35GHz to 6GHz Integer-N Synthesizer.

The LTC®6945 is a high performance, low noise, 6GHz phase-locked
loop (PLL), including a reference divider, phase-frequency
detector (PFD) with phase-lock indicator, charge
pump, integer feedback divider and VCO output divider.

The part features a buffered, programmable VCO output
divider with a range of 1 through 6. The differential, low
noise output buffer has user-programmable output power
ranging from –6dBm to 3dBm, and may be muted through
either a digital input pin or software.

The low noise reference buffer outputs a typical 0dBm
square wave directly into a 50Ω impedance from 10MHz
to 250MHz, or may be disabled through software.

The ultralow noise charge pump contains selectable high
and low voltage clamps useful for VCO monitoring, and
also may be set to provide a V+/2 bias.

All device settings are controlled through a SPI-compatible
serial port.
