Pull Range
The SiT3800 can be factory programmed to provide a completely linear profile. As it’s shown in figure1 and 2,
regardless of the Vdd voltage (1.8V/2.5V/3.3V) the output frequency can be pulled by applying 0V to 1.6V to the
VIN pin. This feature enables a tight control over the pull range by guarantying zero ppm frequency shift at VIN=
0.8V for all the Vdds.
