HPA8

EURO QUARTZ DESCRIPTION HPA8 series LVPECL output oscillators cover the frequency range 60MHz to 320MHz. The part utilizes a crystal operating in third overtone mode (Non-PLL) SPECIFICATION Frequency Range: Output Logic Phase Noise: Frequency Stability: Operating Temp Range Commercial: Industrial: Input Voltage: Output Voltage High '1': Low '0': Rise/Fall Times: Current Consumption: Load: Start-up Time: Duty Cycle: Input Static Discharge Prot: Storage Temperature Range: Ageing: Enable/Disable No connection: Disable: HPA8 LVPECL OSCILLATORS 8 pin Dual-in-Line 60.0MHz to 320.0MHz LVPECL See table See table -10° to +70°C -40° to +85°C +2.5VDC or +3.3VDC ±5% Vdd -1.025V min.
