synthesizer and clock generatorNovatech Instruments, Inc. introduced Model 425A, a Precision 350 MHz DDS Signal Generator packaged in a small shielded table top case. The device generates sine wave, LVDS, and LVCMOS output signals simultaneously. The generated sine wave output frequency is directly programmable in 10 micro-Hz steps from 250 kHz to 350 MHz and includes a built in Prescaler and Divider for generating low jitter LVCMOS clock signals down to less than 2 Hz. The 425A uses the high performance AD9912 DDS IC which has 48-bit Frequency tuning, 14-bit Phase adjustment and a 14-bit reconstruction DAC. The high resolution DAC enables the 425A to achieve low harmonic and spurious distortion. In addition, the 425A has 10-bit Amplitude control and an internal 1.5 ppm temperature compensated crystal oscillator (TCXO) that can be phase locked to an external 10 MHz reference. Locking to a reference gives the device the same stability and accuracy as the reference. When multiple 425A units are locked to the same reference, they remain phase synchronous. A direct clock input up to 1000 MHz can also be selected.
