Functional description
L99LD01

DocID025319 Rev 3
The external resistor applied between pin RSF and ground is setting the converter working
frequency. The voltage applied on pin RSF is the internal reference reported by the source
follower structure which is a constant voltage of 1.21 V. The converter frequency is directly
related to the current flowing through the RSF pin. Figure 12 reports the behavior of
frequency converter as function of the external resistor RSF and IRSF as function of
converter frequency. As above mentioned the converter oscillator spread parameters (dither
effect) are adjustable via SPI.
Dither effect is disabled by default during standalone operation, but it is possible enabling it
simply connecting the SDI pin to 5 V voltage.
