SURFACE-MOUNT OSCILLATORS OUTLINES AND DIMENSIONS XO95 SERIES 6.5mm x 5.0mm High-Specification Oscillator DESCRIPTION Euroquartz XO95 series oscillators consist of a TTL/CMOS compatible hybrid circuit and a miniature quartz crystal packaged in a low-profile ceramic package. Full military testing is available making this an ideal crystal for defence and aerospace applications requiring a highly reliable source of clock signals. FEATURES · · · · · · · · · Suitable for Vapour-Phase, Infrared or Epoxy mount techniques TTL or CMOS compatible Low power consumption Optional Tristate or Standby functions Low EMI emission Supply Voltage 3.3 Volts or 5.0 Volts High shock resistance Full military testing available Hermetically sealed ceramic package SPECIFICATION 1: 2: 3: 4: Output Enable INH (Tristate) or NC Ground Output Vdd POWER DOWN vs. TRISTATE Output Condition Frequency Range: Supply Voltage: Calibration Tolerance* A: B: C: Frequency stability** Temp.
