EXAMPLE:

3HP57-A-125.0

This describes HP62 package PECL, + 3.3Volt supply, ± 25ppm over 0°to

+ 70°C, at frequency of 125.0MHz.

Note: For non-standard frequency stability for commercial temperature

range use the Code’C’ followed by the stability, example ‘C20’ for

± 20ppm over 0° to + 70°C. For industrial temperature range use ‘I’

and the stability, example ‘I20’ for ± 20ppm over -40° to + 85°C.
