HP 10811E 10 MHz Crystal Oscillator

The HP 10811E uses filter feedthrough terminals for power connections and oven monitor. The HP 10811E also has SMB snap-on RF connectors for the 10 MHz output and EFC input, as well as provisions for shock mounting.

• Simplicity and quality of design adds to component reliability
• Low power consumption and low phase noise, suitable for portable applications
• Low aging rate guarantees lower maintenance costs
• Low acceleration means maximum frequency shift of less than ±4 x 10e-9 for any reorientation
• Fast warm-up time -- typically six minutes -- reduces downtime
• Highest value of competitive crystal oscillator products

Frequency Stability:
Long Term (Aging Rate): <5 x 10e-10/day after 24 hour warm-up. 
  (See Notes 1 and 2, and Option Note C.)
Continuous Operation: <1 x 10e-7 per year. (Typical 1 x 10e-8 per year 
  after 1 year.) (See Option Note D.)
Short Term: refer to tables above.
Warm-up: <5 x 10e-9 of final value (the value 24 hours after turn-on) 
  10 minutes after turn-on. See Notes 1 and 3, and Option Note E.

Environmental Sensitivity:
Temperature: <4.5  x 10e-9 from 0° C to +71° C. See Option 
  Note F.
Operating Range: 0° C to +71° C.
Load: <5 x 10e-10 for ±10% change in 50 ohm load. <5 x 10e-10 for 
  ±25% change in 1Kohm load.
Oscillator Power Supply: <2 x 10e-10 for a 1% change in oscillator
  supply voltage. See Option Note G.
Ripple: <-90 dBc spurs from 10 mV rms ripple on oscillator supply 
  voltage at 100 Hz.
Oven Power Supply: <2.5 x 10e-10 for 10% change in oven supply 
  voltage (<1 x 10e-10 typical). See Option Note G.

Adjustment
Coarse Frequency Range: >±1 x 10e-6 (±10 Hz) with 18-turn control. 
  See Option Note H.
Electronic Frequency Control (EFC): >= 1 x 10e-8 (1 Hz) total, control 
  range -5 Vdc to +5 Vdc. See Option Note I.

Power Requirements

Oscillator Circuit: +11.0 to +13.5 Vdc. I = <40 mA (30 mA typical). 
  Ripple <100 µV rms. Turn-on load is 42 ohm minimum. Steady-state power 
  drops to a typical value of 2.0 W at 25° C in still air with 20 
  Vdc applied.

Notes:
  1  For oscillator off-time less than 24 hours and aging rate was 
       <5 x 10e-10 per day before turnoff.
  2  If off-time is greater than 24 hours, specified aging rate will be 
       met in less than 30 days (typically 3 days).
  3  With >20 Vdc on oven, at 25 degrees C ambient.
