The 7311J series has a 155.52 MHz/FEC rate (selectable) with a single CMOS output signal. The 7311K series has a 622.08 MHz/FEC rate selectable) with a single ended sine wave output signal. The 7311Q series has a 622.08 MHz/FEC rate (selectable with a LVPECL complementary output signal. The 7311T series has a 155.52 MHz/FEC rate (selectable) with a PECL complementary output signal. Other frequencies are available. These dual rate VCXOs incorporate two 155 MHz band fundamental crystals, low phase noise bipolar oscillator circuits, and a frequency selectable switch. All of the devices operate on a supply voltage of +3.3 V DC. The 7311J consumes 20 mA typical, the 7311K and 7311T consumes 60 mA typical while the 7311Q consumes 130 mA typical.
