AA OPTO-ELECTRONIC – www.aaoptoelectronic.com
DDSPAxx - DRFAxx VARIABLE FREQUENCY DRIVERS AA OPTO-ELECTRONIC proposes two types of variable frequency drivers. VCOs are analog devices and are suitable for general purpose applications (raster scan, or random access...). The VCO can be modulated (amplitude) from an analog external signal. The frequency is externally controlled by an analog signal. An external power amplifier will be required to generate the RF power levels required by the AO device. DDS models offer high frequency accuracy and stability and extremely fast switching times less than 100ns. They will be preferred to VCOs when high stability and accuracy is necessary. They can be modulated (amplitude) from an analog or digital external signal. The frequency is externally controlled by a digital signal (15 to 31 bits). An external power amplifier will be required to generate the RF power levels required by the AO device.
DDSPAxx Based on DDS (Direct Digital Synthesizers)
DDSPA - Product Overview These Direct Digital Synthesizers are dedicated to high accuracy applications for which high resolution is the key factor. A PC interface board will be used to control the frequency (15-31 bits) as well as the latch of the frequency (1 bit E/D). These drivers are used in combination with AA amplifiers. They are suitable for agile frequency shifters and deflectors. DDSPA - Features Variable frequency [20..400MHz] AM control:
bits 8 digital 0-5V/analog
FM control: bits 15/23/31 digital Rack available with 2 outputs (XY deflection )
DRFAxx Based on VCO (Voltage Controlled Oscillators)
DRFA - Product Overview These Voltage Controlled Oscillators are the simplest way to control a deflector or a variable frequency shifter, in random access or raster scan mode. A voltage between 0 and 10V is applied on the frequency control input for sweeping between Fmin and Fmax and here the sweeping time can as low as 1µs. The typical stability of the VCO driver is 50 to 100 KHz/°C. For sharpest application, the DDS driver will be preferred. These drivers need to be associated with AA amplifiers (OEM version only). DRFA - Features Variable frequency: octave one to up AM control (Analog) FM control (Analog) Rack available with 2 outputs (XY deflection) RoHS
