REV. 1.0.2 7/26/01
Features
Programmable output frequency – DC to 50kHz
Low gain error and total harmonic distortion
3-wire SPI compatible serial microprocessor interface
with double buffered data latch
Fully integrated solution – no external components
required
Frequency resolution of 1.5Hz (±0.75Hz) with a 12MHz
clock input
Onboard 3 to 12MHz crystal oscillator
Clock outputs of 1/2 or 1/8 of the input clock frequency
Synchronous or asynchronous data loading capability
Compatible with ML2004 logarithmic gain/attenuator
General Description
The ML2036 is a monolithic sine wave generator whose
output is programmable from DC to 50kHz. No external
components are required. The frequency of the sinewave
output is derived from either an external crystal or clock
input, providing a stable and accurate frequency reference.
The frequency is programmed by a 16-bit serial data word.
The ML2036 provides for a V
or ±V
REF
/2. Also included with the ML2036 is an inhibit
function which allows the sinewave output to be held at zero
volts after completing the last half cycle of the sine wave in
progress. Two digital clock outputs are provided to drive
other devices with one half or one eighth of the input clock
frequency.
OUT
amplitude of either ±V
REF
The ML2036 is intended for telecommunications and
modem applications that need low cost and accurate genera-
tion of precise test tones, call progress tones, and signaling
tones.
