| EURO QUARTZ DESCRIPTION HPW576 series LVPECL output oscillators cover the frequency range 750kHz to 800MHz. The part contains a high 'Q' fundamental crystal and multiplier circuit. SPECIFICATION Frequency Range: Output Logic Phase Noise: Frequency Stability: Operating Temp Range Commercial: Industrial: Input Voltage: Output Voltage High '1': Low '0': HPW576 LVPECL OSCILLATORS 7x5mm SMD 6 pad 750.0kHz to 800.0MHz LVPECL See table See table -10 to +70C -40 to +85C +3.3VDC 5% OUTLINE & DIMENSIONS Vdd -1.025V min. Vdd -1.620V max. (RL = 50W to Vdd -2.0V) Rise/Fall Times: 1.5ns typical (20% Vdd to 80% Vdd) Current Consumption (15pF load): <24MHz: 25mA max. 24.01 to 96MHz: 65mA max. 96.01 to 700MHz: 100mA max. 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. Storage Temperature Range: -55C to +150C Ageing: 3ppm per year max., 2ppm thereafter. At T amb +25C 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.
