General Description
The DS1094L is a silicon oscillator that generates four
multiphase, spread-spectrum, square-wave outputs.
Frequencies between 2MHz and 31.25kHz can be out-
put in either two, three, or four-phase mode. The inter-
nal master oscillator can be dithered by either 0, 2, 4,
or 8% to reduce the amount of peak spectral energy at
the fundamental and harmonic clock frequencies. This
significantly reduces the amount of electromagnetic
interference (EMI) radiation that is generated at the sys-
tem level. The DS1094L is ideally suited as a clock gen-
erator for switched-mode power supplies. The outputs
generated by the DS1094L are used by DC-DC circuit-
ry to efficiently shift voltages either up or down. The
DS1094L can be programmed using the I2C-compati-
ble, 2-wire serial interface to select the output frequen-
cy, number of clock phases, and dither rate, or
optionally it can be shipped from the factory custom
programmed.
