HPA8

      The HPA8 series(8 pin Dual-in-Line) are a kind of  LVPECL output oscillators cover the frequency  range 60MHz to 320MHz. The part utilizes a crystal operating  in  third overtone mode (Non-PLL).
      Some parameters of the HPA8 series are got, frequency Range(60.0MHz to 3200.0MHz), Output Logic(LVPECL), Phase Noise(See table), Frequency Stability(See table), Operating Temp Range(Commercial:  -10° to +70°C; Industrial:  -40° to +85°C), Input Voltage: +2.5V to +3.3VDC ±10%), Output Voltage(High '1':  Vdd -1.025V min.; Low '0':  Vdd -1.620V max.((RL = 50W to Vdd -2.0V)), Rise/Fall Time(0.25ns typical, 0.5ns max.)(20%Vdd to 80%Vdd)), Current Consumption(75mA max. at 212.50MHz), Load(50W into Vdd-2.0V), Start-up Time(5ms typ., 10ms max), Duty Cycle(50% ±5% (at Vdd -1.3V), Input Static Discharge Prot(2kV min), Ageing(±3ppm per year max., ±2ppm thereafter. At T amb +25°C), Storage Temperature Range(-55°C to +150°C), Enable/Disable(No connection: Both outputs enabled; Disable: Both outputs are disabled when control pad is taken below 0.3V referenced to ground. Oscillator is always 'on'. (Special request - oscillator is off when disabled.); Enable:  Both Outputs are enabled when control pad is taken above 0.7 Vcc referenced to ground.).
      Then the HPA8 series' supply Voltage(+4.6 VDC max), Input Voltage Vi(Vss-0.5 min., Vdd +0.5V max), Input Voltage Vo(Vss-0.5 min., Vdd +0.5V max) are also got.
