PCM-1211 PCM-1211 PRODUCT CHANGE NOTIFICATION PCN#: PCM-1211 PCM-1211 PCN Date: 7 November 2006 Product Families Affected Crystal Resonator: Model 407, Surface Mount Quartz Crystal Reason For Change In an effort to easily distinguish between Fundamental and Third Overtone mode crystals and accommodate three-digit frequency values (i.e. 100 MHz), CTS is modifying the catalog part number format for the Model 407 product family. Description For Change The current catalog part number format does not contain an identifier for the oscillation mode of the associated frequency and can only specify two-digit crystal frequencies (i.e. 99 MHz). ORDERING INFORMATION 407 M OPERATING TEMPERATURE RANGE FREQUENCY IN MHz C = -20°C to +70°C (standard) I = -40°C to +85°C M - indicates MHz and decimal point. Frequency is recorded with minimum 5 significant digits to the right of the "M". FREQUENCY TOLERANCE @ 25°C LOAD CAPACITANCE 1 = ± 10 ppm 2 = ± 20 ppm 3 = ± 30 ppm (standard) A = 10 pF B = 13 pF C = 16 pF D = 18 pF E = 20 pF F = 24 pF STABILITY TOLERANCE Over Operating Temperature Range (Referenced to 25°C Reading) 1 2 3 4 5 = = = = = ± ± ± ± ± 10 20 30 40 50 ppm * ppm ppm ppm ppm (standard) * Limited to Standard Operating Temperature Range Only, Code C.

Use form C052 to detail non-standard parameters. Contact your local CTS Representative or CTS Customer Service for assistance. 1 of 3 PCM-1211 PCM-1211 CTS will change the part number format to include a new designator, after the 407, for identifying Fundamental or Third Overtone mode. In order to accommodate the new designator the Operating Temperature Range and Stability Tolerance will be combined into a one code identifier. To accommodate a three-digit frequency the format will change from xxMxxxxx to xxxMxxxx. The new 15-character part number format will be expressed as follows. ORDERING INFORMATION 407 M MODE OF OSCILLATION F = Fundamental T = 3RD Overtone FREQUENCY IN MHz M - indicates MHz and decimal point. Frequency is recorded with minimum 4 significant digits to the right of the "M".

Implementation This change is effective immediately for the generation of new Model 407 catalog part numbers. Existing catalog part numbers under the old format will not change and will remain valid. Old format part numbers with frequencies less than or equal to 48.0000 MHz will be considered as Fundamental mode designs. Frequencies above 48.0000 MHz will be Third Overtone mode designs. See list of active Old Format part numbers and their mode designation below. If a frequency between 30.0010 MHz and 48.0000 MHz, under the old part number format, requires a Third Overtone oscillation mode then a new part number will need to be assigned.
