OCXO performance in TCXO size
IQD has announced a newsurfacemount OCXO, claimed by its manufacturer, Rakon, to offer previously unheard of performance in a compact style measuring 9.7 by 7.5 by 4.1mm.With stabilities down to
±20ppb over an operating temperature range of -40 to 85°C, the new IQOV-40 series offersOCXOperformance in TCXOsize.
Frequency can be specified anywhere between five and 50MHz
with standard frequencies of 10, 12.8, 19.2 and 20MHz available on short lead times. These common frequenciesmake the newIQOV-40 series suitable for applications such as digital signal processors, telecommunications transmission hubs, cellular base stations and test equipment.
Multiple versions allowoperationwith either a 3.3 or a 5.0V power
supply and either a clipped sinewave or HCMOS output. Phase noise figures are typically -125dBc/Hz at 100Hz away fromcarrier and - 150dBc/Hz at 100kHz away fromcarrier. Current consumption is less than 400mWsteady state and frequency stability ±10ppb over the commercial temperature range of -20 to 70°C.

Targeted at automotive applications and fast turnaround prototypes, HC-49/U SMD crystals are now available fromTotal Frequency Control with a delivery time of one week. Standard and customfrequencies are available along with precision tolerances.
With fourmounted corners, the crystals are said to be incredibly stable
and their footprint is compatiblewithmany popular SMD devices, including TFC'sMG3A package and 49SXT packages. TypicalQfactors are 100,000with ageing from±1ppmfor the first yearmaximum.
Assistantmarketingmanager,Meghan Hinch, said: “This product
has all the qualities of precision crystals in a fastmake SMD package.”
