A design suited to PC board slot mounted applications. A simplified functional block diagram is shown in Figure 3. Many commercial applications for precision frequency standards demand performance over an expended temperature range. Often frequency variation with temperature is the performance range. Often frequency variation with temperature is the performance-limiting feature of these devices for CDMA holdover applications. The two products described in this paper have both been designed to operate over extended temperature ranges while guaranteeing a frequency variation of less than 1E-10. The FE-5680A operates at any temperature between-10 and +60 deg. C. A temperature range required for indoor rack-mounted telecommunication hardware with limited air flow. The FE-5652A operates at any temperature between-40 and +85 deg. C, a temperature range required for outdoor, limited access, low maintenance telecommunication hardware. FREQUENCY vs. TEMPERATURE Frequency variations due to ambient temperature variations can easily swamp other sources of instability for a Rb frequency standard operating in a real life environment. Therefore. Special attention was given to frequency stability vs. temperature in these designs. Figure 5 and 5 show typical performance data for FE-5680A and FE-5652A. Rb standards over the ambient temperature range. In addition to the information provided by these plots, it is useful to u
