DS1094L
Detailed Description
The DS1094L consists of a master oscillator, prescaler,
phase generator, and triangle-wave generator (used to
dither the master oscillator), which are all programma-
ble using the 2-wire interface and stored in NV memory.
Master Oscillator
The master oscillator is responsible for generating the
timing (frequency) of the outputs. The master oscillator
frequency, fMOSC, can be programmed anywhere
between 1MHz to 2MHz in 100kHz steps. The master
oscillator is programmed using the DAC register. The four
MSBs of the DAC register are don’t cares, while the four
LSBs (D3 to D0) are the DAC value. The master oscillator
frequency is determined using the following equation:
fMOSC = 1MHz + (DAC value x 100kHz)
Valid values for DAC are 0 to 10 (dec). DAC values
greater than 10 exceed the 2MHz limit and are not per-
mitted.
The master oscillator also determines the spread-spec-
trum dither frequency. This is described in the Triangle
Wave Generator section.
