DESCRIPTION
HDF576 series LVDS output oscillators cover the frequency range 38MHz to 640MHz. The design contains a high 'Q' fundamental crystal and utilizes a low jitter multiplier circuit. Integrated phase jitter is 0.5ps maximum. OUTLINE & DIMENSIONS Frequency Range: 38.0MHz to 640.0MHz Output Logic LVDS 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 Logic High '1' V OH: 1.4V typical, 1.6V max. Low '0' V OL: 0.9V min., 1.1V typical Differential Output Voltage VOD: 247mV min., 355mV typ., 454mV max. Output 1 - Output 2 Differential Output Error dVOD: -50mV min., 50mV max. Offset Magnitude Error dVOS: 0mV min., 3mV typ., 25mV max. Rise/Fall Times: 0.7ns typical, 1.0ns max. (20% to 80% of LVDS waveform) Current Consumption (15pF load): 38MHz to 100MHz: 45mA max. 100.01 to 320MHz: 60mA max. 320.01 to 640MHz: 70mA max. Load: 50 W from each output Start-up Time: 5ms typ., 10ms max. Duty Cycle: 50%±5% (at 1.5V) Drive Capability: 100 Ohms between outputs 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: +4.6VDC max. Input Voltage Vi: Vss -0.5 min., VDD +0.5V max. Input Voltage Vo: Vss -0.5 min., Vdd +0.5V max.
