Extended Temperature/COTS XO, 3.3V 20KHz to 100MHz Features 3/4 3/4 3/4 3/4 3/4 3/4 3/4 RoHS Status Tiny 5X7 SMD form factor Hermetically sealed for rugged environmental conditions Extremely wide operating temperature range accommodates harsh environments All crystals are processed in-house with tight angle control to assure best frequency-temperature characteristics All units are vacuum baked before sealing at 175C for 16 hours to eliminate moisture traces and pre-age units for superior stability Tristate feature optional Equivalent 5V parts are available in series T1254 Applications 3/4 Any electronic circuit requiring 3.3V HCMOS clocking that is exposed to very high or very low temperatures such as oil drilling or weather observation equipment Description Owing to their small size, light weight, and rugged characteristics, these 3.3V HCMOS extended temperature/COTS oscillators fulfill tasks not previously feasible. They are used in applications that take advantage of their extended temperature range and high performance. Twenty six different models (with and without tristate) cover -55C to +200C operation and provide frequency selection from 20KHz to 100MHz. They combine excellent long-term reliability, loading characteristics, and superior startup performance.
