DS4006-1.4
QC6313 Series
4 to 25MHz TEMPERATURE COMPENSATED QUARTZ CRYSTAL OSCILLATORS
The QC6313 temperature compensated crystal oscillator provides a frequency output between 4MHz and 25MHz which is HCMOS and LSTTL compatible. Over the temperature range -40°C to +85°C frequency stability is as low as ±1ppm. Housed in an industry standard package, the QC6313 provides for a low cost solution when a highly stable reference is required.

MARKING The following information is indelibly marked on the top surface of each device and on each primary package: 1. GPS Logo 2. The type number 3. The nominal output frequency in 'MHz' 4. The offset (Hz) to be applied at 25°C 5. The date code in accordance with Clause 22 of BS9000: Part 1: 1981 6. The primary package is marked to indicate device static sensitivity
GENERAL NOTES
STATIC PRECAUTIONS All quartz crystal oscillators can contain devices which are deemed to be static sensitive. Full handling precautions must be followed at all times when dealing with these devices. Failure to do so may result in damage to the product. A useful guide is BS CECC 00015 : Part 1 : 1991, Protection of Electrostatic Devices.
MECHANICAL PRECAUTIONS
Handling Care must be taken to avoid damage to pins, particularly when glass to metal seals have been used in the manufacture of the device. This can lead to loss of hermeticity which can impair the long term performance of the unit. GPS product is built to withstand normal assembly practices, however, excessive levels of shock or vibration may result in degraded performance or in extreme cases total failure of the product.
ORDERING INFORMATION
When Ordering Please Quote: 1. The series number: QC6313 2. The reference number from the above specification: eg. ref 1A-2A 3. The required frequency Our Sales Desk will be happy to advise upon any other parameters which require more detailed attention.
SPECIFICATION VARIATIONS
In the event that your requirements are not entirely met by this specification you should note that varients of this series are available. Indeed this device can be fully customised to your exact specification. For details of this please contact our Sales Desk.
