## **7 x 5mm SMD HCMOS** 

**Miniature 7.0 x 5.0 x 1.4mm hermetically-sealed package Frequency Range 500kHz to 125MHz Tristate (Enable/Disable) function as standard Supply voltage range 1.8, 2.5, 3.3 or 5.0 Volts** 

## **DESCRIPTION** 

## **OUTLINE & DIMENSIONS** 

## **Page 1 of 2** 

XO91miniature oscillators consist of a TTL/CMOS-compatible hybrid circuit together with a miniature quartz crystal packaged in a lowprofile, industry-standard ceramic package. The high quality design and materials employed provide a highly reliable clock oscillator in a miniature package while mass production methods ensure that the XO91 provides a cost-effective oscillator solution.

**SOLDER TEMPERATURE PROFILE** 

* Frequency stability is inclusive of calibration tolerance at 25°C, frequency change due to shock & vibration, ±10 supply voltage variation and stability over temperature range. 

_Note: Parameters are measured at ambient temperature of 25°C, supply voltage as stated and a load of 15pF_
