DESCRIPTION
HPF8 series LVPECL output oscillators cover the frequency range 38MHz to 640MHz. The part contains a high 'Q' fundamental crystal and utilizes a low jitter multiplier circuit. OUTLINE & DIMENSIONSFrequency Range: 38.0MHz to 640.0MHz 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 or +3.3VDC ±5% Output Voltage High '1': Vdd -1.025V min. Low '0': Vdd -1.620V max. (RL = 50 W to Vdd -2.0V) Rise/Fall Times: 0.7ns typical (20% Vdd to 80% Vdd) Current Consumption (15pF load): 38MHz to 100MHz: 65mA max. 100.01 to 320MHz: 80mA max. 320.01 to 640MHz: 90mA max. Load: 50 W 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. Storage Temperature Range: -55°C to +150°C Ageing: ±3ppm per year max., ±2ppm thereafter. At T amb +25°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. ABSOLUTE MAXIMUM RATINGS (Permanent damage may be caused if operated beyond these limits.) Supply Voltage Vdd: +4.6V max. Input Voltage Vi: Vss -0.5 min., VDD +0.5V max. Input Voltage Vo: Vss -0.5 min., Vdd +0.5V max.
