| CFPV-7 Low Power Miniature SMD VCXO ISSUE 4 - draft; 4 OCTOBER 2004 Delivery Options VoL: <10% Vs Tri-state control (6 pad package only) Control Input Logic `0' (< 30% Vs) will put the output in the tri-state mode Control Input Logic `1' (> 70% Vs) or left unconnected will enable the output `Active High' is standard but a version with `Active Low' can be supplied on request Please contact our sales office for current leadtimes Description Voltage controlled crystal oscillator (VCXO) with crystal packed into its own holder Grounded crystal enclosure acts like a shield and provides low EMI Non PLL based design ensures low jitter 3.3V or 5V supply voltage CMOS, PECL, SINE or LVDS Output Single Ended or Differential PECL Output (option) Load: 50 to Vs-2V Duty Cycle @ 50%: 40/60% Rise & Fall Time (20%-80%): < 0.5ns typ. VoH: 2.4V typ. @Vs=3.3V VoL: 1.5V typ. @Vs=3.3V Tri-state control The output is enabled if tri-state control is:a) Left open circuit b) Connected to GND c) Connected to a voltage <(Vs-1.65V) = PECL logic low The output is disabled if tri-state control is:a) Connected to Vs b) Connected to a voltage >(Vs-0.96V) = PECL logic high When disabled, pad 5 goes low and pad 4 goes high. The tri-state control pad has an internal 75k pull down to GND resistor RoHS Compliance Parts with the suffix `LF' on the part number are fully comliant with the European Union directive 2002/95/EC on the restriction of the use of certain hazardous substances in electrical and electronic equipment. Note: The RoHS compliant parts are suitable for assembly using both Lead-free solders (see Lead-free Reflow soldering profile) and Tin / Lead solders (see Tin / Lead Reflow soldering profile) SURFACE MOUNT VCXOs Standard Frequencies 8.192, 20.0, 24.576, 32.768, 34.368, 38.88, 39.3216, 44.736, 50.0, 51.84, 52.0, 61.44, 63.8976, 77.76, 80.0, 82.3341, 140.0, 155.52MHz Sine Output (option) Frequency Range Load: 50 Level: can be specified up to +8dBm Harmonics: < -20dBc 2.0 to 170MHz Package Outline 4-pad (style 578) or 6-pad (style 579) Industry Standard, Glass Epoxy laminate (FR4) based with standard Tin/Lead solder finish end terminations and High Temperature Plastic cover LVDS Output (option) Load: 100 differential +10pF each output to GND Diff. output voltage: 250mV min. 400mV max. Duty Cycle @ 50%: 40/60% Rise & Fall Time (20 to 80%): <0.5ns typ. Tri-state control (6 pad package only) Control Input Logic `0' (0.8V) will put the output in tri-state mode Control Logic'1' (>2.0V) will enable the output Supply Current 3.3V 5% (option) 5.0V 5% (option) Supply Voltage Ranging from typ. 10mA @ 2MHz/3.3V CMOS to typ. 80mA @ 170MHz/5V PECL, at nominal load.
