1 / 1 page EURO QUARTZ EUROQUARTZ LIMITED Blacknell Lane CREWKERNE Somerset UK TA18 7HE Tel: +44 (0)1460 230000 Fax: +44 (0)1460 230001 Email: info@euroquartz.co.uk www.euroquartz.co.uk 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) Frequency Range: 60.0MHz to 320.0MHz 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: +2.5VDC or +3.3VDC ±5% Output Voltage High '1': Vdd -1.025V min. Low '0': Vdd -1.620V max. (RL = 50W to Vdd -2.0V) Rise/Fall Times: 0.25ns typical (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. 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. SPECIFICATION PART NUMBERS HPA8 oscillator part numbers are derived as follows: Example: 3HPA8-A-250.000 HPA8 LVPECL OSCILLATORS Supply Voltage 3 = 3.3VDC 25 = 2.5VDC Series Designation Package Style Stability Code (See table) Frequency STABILITY OVER TEMPERATURE RANGE Stability Temperature Range Order Code ±ppm °C 25 -10 to +70 A 50 -10 to +70 B 100 -10 to +70 C 25 -40 to +85 D 50 -40 to +85 E 100 -40 to +85 F Offset 10Hz -65 100Hz -95 1kHz -120 10kHz -128 100kHz -122 1MHz -120 10MHz -140 dBc/Hz PHASE NOISE (155.250MHz) JITTER Integrated Phase Jitter: 0.25ps typical at 155.520MHz (12kHz to 20MHz) Period Jitter (RMS): 3.0ps typical at 155.520MHz Period Jitter (peak to peak): 21ps typical at 155.520MHz OUTLINE & DIMENSIONS 8 pin Dual-in-Line |
