QUARTZ

7 x 5mm High Frequency HCMOS Oscillator

Industry-standard 7.0 x 5.0mm SMD package

Frequency Range 125MHz to 320.0MHz

High Q crystal and ultra-low jitter multiplier circuit

Supply voltage 2.5 Volts or 3.3 Volts

LVCMOS outputs at frequencies from 125MHz to 320MHz. A high Q

crystal and ultra-low jitter multiplier circuit provide extremely good

performance. An enable/disable function is standard and the

oscillator may also be specified with a power down function.

Frequency Range: 125.0MHz to 200.0MHz (15pF load)

125.0MHz to 320.0MHz (10pF load)

Output Logic: LVCMOS

Integrated Phase Jitter: 0.4ps typical 0.5ps max

(12kHz ~ 20MHz) at 155.520MHz

Period Jitter RMS: 3ps typical, 5 ps max. at 155.520MHz

High '1': 90% Vdd minimum

Low '0': 10% Vdd minimum

Rise/Fall Time: 2.4ns typical, 15pF load.

(20%Vdd to 80%Vdd)

Current Consumption: 40mA max.

Load: 15pF

Start-up Time: 5ms typical, 10ms maximum

Duty Cycle: 50% ±5% (Measured at Vdd-1.3V)

Static Discharge Protection: 2kV maximum

Ageing: ±3pmm max. first year then ±2ppm

Input Voltage Vo: Vss-0.5 min., Vdd +0.5V max.

DISABLE Output is disabled when enable/disable pad is

taken below 0.3 Vcc referenced to ground

Oscillator is continues to run.

ENABLE Oscillator is enable when enable/disable Pad is

taken above 0.7 Vcc referenced to ground.

POWER DOWN Available by special request: Oscillator shuts down

when disabled.
