VL-821
CMOS Crystal Oscillator Previous Vectron Model VCS3
VL-821
Description
Vectron's VL-821 Crystal Oscillator (XO) is a quartz stabilized square wave generator with a CMOS output, operating off either a 1.8, 2.5, or 3.3
volt supply. The VL-821 utilizes a high performance, low frequency quartz resonator followed by a custom ASIC to synthesize the output frequency.

A 0.01 uF and a 0.1uF capacitor should be located as close to the supply as possible (to ground). VDD supply ramp should be <100 msec. Figure 2 defines these parameters. Figure 1 illustrates the operating conditions under which these parameters are tested and specified. Symmetry is measured defined as On Time/Period. Includes calibration tolerance, operating temperature, supply voltage variations, aging and shock and vibration (not under operation). Output will be enabled if the Enable/Disable is left open. E/D should be powered up after VDD.

Reliability
VI qualification includes aging at various extreme temperatures, shock and vibration, temperature cycling, and IR reflow simulation. The VL-821 family is capable of meeting the following qualification tests: Table 5. Environmental Compliance Parameter
Mechanical Shock Mechanical Vibration Temperature Cycle Solderability Gross and Fine Leak Resistance to Solvents Moisture Sensitivity Level
Conditions
MIL-STD-883, Method 2002 MIL-STD-883, Method 2007 MIL-STD-883, Method 1010 MIL-STD-883, Method 2003 MIL-STD-883, Method 1014 MIL-STD-883, Method 2015 MSL 1
Contact Pads Gold over Nickel Typical Characteristics - Phase Noise and Gain Curve
Although ESD protection circuitry has been designed into the VL-821 proper precautions should be taken when handling and mounting. VI employs a human body model (HBM) and a charged device model (CDM) for ESD susceptibility testing and design protection evaluation. Table 6. ESD Ratings Model

Stresses in excess of the absolute maximum ratings can permanently damage the device. Functional operation is not implied at these or any other conditions in excess of conditions represented in the operational sections of this datasheet. Exposure to absolute maximum ratings for extended periods may adversely affect device reliability. Permanent damage is also possible if E/D is applied before VDD. Table 7.

IR Reflow
The VL-821 is qualified to meet the JEDEC standard for Pb-Free assembly. The temperatures and time intervals listed are based on the Pb-Free small body requirements. The VL-821 device is hermetically sealed so an aqueous wash is not an issue.
