C-TYPE 3.3, 5.0 volt CMOS Oscillator Not recommended for new designs Features • CMOS output • Output frequencies to 190 MHz • Low jitter, Fundamental or 3rd OT Crystal • Tri-state output for board test and debug • Gold over nickel contact pads • Hermetically sealed ceramic SMD package • Product is compliant to RoHS directive and fully compatible with lead free assembly The C-TYPE Crystal Oscillator Applications • SONET/SDH/DWDM • Ethernet, Gigabit Ethernet • Storage Area Network • Digital Video • Broadband Access • Microprocessors/DSP/FPGA fo Output Buffer / Disable Description Vectron’s C-TYPE Crystal Oscillator (XO) is quartz stabilized square wave generator with a CMOS output, operating off a 1.8, 2.5, 3.3, or 5.0 volt supply. The C-TYPE uses fundamental or 3rd overtone crystals resulting in low jitter performance, typically 0.5ps rms in the 12 kHz to 20MHz band. Also a monolithic IC, which improves reliability and reduces cost, is hermitically sealed.

When the E/D is set to a logic low, the oscillator stops and the output is in a high impedance state. This helps reduce power consumption as well as facilitating board testing and troubleshooting. Tri-state Functional Description Under normal operation the tri-state is left open or set to a logic high state. When the tri-state is set to a logic low, the oscillator remains active but the output buffer is in a high impedance state. This helps facilitate board testing and troubleshooting. Table 3.

VI employs a Human Body Model and a Charged-Device Model (CDM) for ESD susceptibility testing and design protection evaluation. ESD thresholds are dependent on the circuit parameters used to define the model. Although no industry wide standard has been adopted for the CDM, a standard HBM of resistance = 1.5kohms and capacitance = 100pF is widely used and therefore can be used for comparison purposes.
