The STEL-1377Q is a complete Quadrature Direct
Digital Frequency Synthesizer (DDS) in a single DIL
package measuring only 3.75 x 1.6". The STEL-1377S
provides a single ended output only. The STEL-1377
makes it possible to use DDS technology in
applications requiring quadrature outputs as well as
frequency and phase modulation in a small package.
The STEL-1377 is a printed circuit unit using the STEL-
1177 PM and FM Numerically Controlled Oscillator
(NCO) chip driving two high-speed 10-bit DACs
(Sony CX20201A-1) to generate quadrature analog
output signals. Surface mount technology (SMT)
components are used throughout.
The device is
guaranteed to operate at clock frequencies up to 60
MHz over the temperature range of 0-70
°C, giving an
output frequency range of 0 to over 25 MHz, with a
frequency resolution of 14 milliHz at a clock frequency
of 60 MHz. In addition, the device features phase and
frequency modulation capabilities at extremely high
modulation rates, up to 25% of the clock frequency. For
more detailed information on the STEL-1177 NCO
please refer to the STEL-1177 data sheet. For more
information on the DAC please refer to the Sony
CX20201A-1 data sheet. The output frequency is
directly related to the clock frequency by the
following:
fc x -Phase
fo=
232
where:
fo is the frequency of the output signal
and:
fc is the clock frequency.
