Q2368

The Q2368 is designed as dual direct digital synthesizer. Its typical applications include quadrature oscillators, cellular base stations, magnetic responce imaging / medical systems, RADAR systems and simulators, paging systems, high performance test equipment, digital ratios and modems, HF transceivers and local oscillator generation for VAST, DBS and GPS applications and so on.

Q2368 has many features. The first one is single high-speed DDS up to 130MHz or two independent DDSs, each up to 65MHz clock speed. The next one is 32-bit input resolution for frequency and phase. The next one is 12-bit output resolution for sine wave amplitude. The next one is noise reduction circuit. The next one is 8-bit bus control or serial control interface. The next one is programmable HOP clock mode. The next one is HOPOUT signal (output trigger pulse). The next one is chirp mode (linearity frequency sweep function). The next one is programmable chirp rate. The next one is BURP control (hold signal function). The next one is power down mode. The next one is modulation control : BFSK, BPSK, QPSK, 8-PSK, I/Q using both channels. The next one is 14 X 14 mm, 100-pin PQFP package. The next one is guaranteed over industrial temperature and voltage range. That are all the main features.

Some absolute maximum ratings of Q2368 have been concluded into several points as follow. The first one is about its storage temperature range which would be from -65°C to +150°C. The next one is about its junction temperature which would be +150°C. The next one is about its voltage on any input or output pin which would be min -0.3V and max Vdd+0.3V. The next one is about its supply voltage which would be min -0.3V and max +7.0V. The next one is about its I/O electrostatic discharge protection which would be min -2000V and max +2000V. The next one is about its I/O latch-up trigger current protection which would be min -150mA and max +150mA. And so on. For more information please contact us.
