OSC-15802 ® SYNCHRO/RESOLVER/INDUCTOSYN REFERENCE OSCILLATOR DESCRIPTION FEATURES The OSC-15802 is a power oscillator with two outputs that are 90° out of phase. These outputs provide both the reference and quadrature signals, simultaneously, making the OSC15802 ideally suited for synchro, resolver, Linear Variable Differential Transformer (LVDT), Rotary Variable Differential Transformer (RVDT) and Inductosyn applications. The oscillator’s outputs are pin-programmable for both frequency and amplitude. The output frequency can be programmed from 400 Hz to 10 kHz by simply connecting two exter- nal capacitors. The Reference output voltage, 7 Vrms, can be scaled down by connecting a single resistor. • ADI Alternate Source • Quadrature Reference Output Voltages for Inductosyn Applications APPLICATIONS Packaged in an 18-pin hermetic DDIP, the OSC-15802 operates over a temperature range of -55°C to +125°C. This, combined with its small size and programmable output voltage and frequency capabilities, makes it an excellent choice for synchro, resolver, LVDT, RVDT and Inductosyn applications. • Programmable Output Frequency to 10 kHz • Small 18-Pin DDIP • Scalable Reference Output • -55°C to +125°C Operating Temperature Range G = +2.8 Cext C1 +15 VDC Rext GND - PA IN PA OUT QUAD OSCILLATOR + REF OUT -15 VDC C2 Cext 5350 Ω REF OUT +90˚ FIGURE 1.

PARAMETER UNITS FREQUENCY Hz OUTPUTS PA OUT Voltage Current REF Voltage Current REF +90° Voltage Current Protection The output frequency of the OSC-15802 is programmable to 10 kHz. The frequency is programmed using two external equal value capacitors (see FIGURE 2). The value of the capacitors (Cext) is calculated as follows: VALUE Programmable from 400 to 10k Cext = 10 f V rms 7 ±1% for 2.5 V input mA rms 190 min where: Cext is capacitance in picofarads (use NPO ceramic), V rms 2.5 ±10% mA rms 3 min f is frequency in Hertz. V rms 2.5 ±10% mA rms 3 min Momentary short circuit and transient proof (1 sec. max.) POWER SUPPLIES Voltage Current Max Voltage without damage Vdc mA Vdc TEMPERATURE RANGE Operating -10X -30X Storage 7 To scale down the PA OUT voltage, an external resistor (Rext) is connected between pins 3 and 7. The value of Rext is calculated as follows: Rext = 37.5 - 5.35 Vout ±15 ±5% 20 max plus current load ±18 where: Rext is in kOhms, Vout is the desired voltage in Vrms. °C °C °C PHYSICAL CHARACTERISTICS Size in (mm) oz (gm) Weight -55 to +125 0 to +70 -65 to +150 1.0 x 0.8 x 0.2 (25.45 x 20.32 x 4.83) 18 pin DDIP 0.4 (1) +15 V 18 11 -15 V 16 15 C2 Cext REF OUT +90˚ 12 6 C2 13 OSC-15802 C1 PA OUT (REF) Cext 7 REF OUT PA IN 3 Rext FIGURE 2.
