2” X 2” (Low Distortion) 1 Hz to 102.4 kHz Oscillators: Dual Channel 8 or 9-Bit Frequency Selectable & Quadrature

Description

The SPPOS C Series is a compact, dual channel, phase continuous, DSP based, prog rammable si ne wave generator with an alog outputs an d 8 or 9 bits of frequency selection. All SPPOSC-01 platforms are small, low profile, easy to use signal generators, which require n o e xternal comp onents and can cover th e audio/ultrasonic bandwidth from 1 Hz to 102.4 kHz in several standard and custom frequency ranges. SPPOSC’s use a fixed point DSP with 32-bit math, 24- bits of resolution and dual channel DACs. Noise floo r and distortion are typically –100dB to 20 kHz and < – 80 dB to 100 kHz. Features/ Benefits:

  • Available in a si ngle, dual o r q uadrature (0.1° phase stability) form fa ctor, SPPOSC oscillators with up to 512 tuning steps insure design flexibility in a compact 2” x 2” footprint while minimi zing board space requirements.
  • This plug -in, turnkey si gnal sou rce, with a standard or cu stom al gorithm, all ows product designers to inco rporate variou s p recision o n- board p rogrammable si gnal g enerators i n a standard pin-out and form factor thereb y reducing design time while maximizing design flexibility.
  • When us ed in conjunc tion with the SPPDB-01 development board, SPPOCS si gnal generators require minimal set-up time to p rovide low noi se and di stortion sign als fo r laboratory ev aluation o r precision field installations.

For dual Channel 8-Bit programming D8 is Channel Select and re quires a mini mum of 21 µse cs set-up time at a logic “1”, 5volts for channel 2 or logic “0”, 0 volts, for Channel 1 3. For an 8-bit dual ch annel unit, the Program enable or “Latch pin” is D9. To enable a p rogram change, this pin must be pulled to a logic high “1” or 5 volts. If the pin is low, a frequency change will not be read and th e chan nels will continue to run t he p revious values. 4. The D0 – D 9 bus data are checked simultaneously. New fre quency sele ction data mu st b e present o r updated at t he time Channel select o ccurs to be valid. The Progra m ena ble or “L atch” pin must b e high. While the latch pin is high, the Frequency data must remai n on the bus until the u ser applie s the next frequency change. The pins do not float during programming! The frequency ports are polled by the system every 21 µ seconds. Within 21 µ secs of programming, if the latch goes low, the programmed values are retained and the pins may float.
