Description:
Connor-Winfield's PCxxx and
LCxxx series are 5x7mm surface
mount, fixed frequency crystal
controlled oscillators (XO) designed
for applications requiring tight
frequency stability, wide temperature range,
and low jitter. Operating at 2.5 or 3.3Vdc
supply voltage, the PCxxx series provides
LVPECL differential outputs, while the LCxxx
provides LVDS differential outputs.
Both series incorporate PLL multiplication
to achieve the final output frequency from a
lower frequency crystal reference.
Features:
• Frequency Range 15 MHz to 2.0 GHz
• 3.3 or 2.5 Vdc Operation
• 5x7 mm SMT Package
• Frequency Stabilities Available:
±20 ppm, ±25 ppm, ±50 ppm
or ±100 ppm
• Temperature Ranges Available:
0 to 70°C, -40 to 85°C, 0 to 85°C
or -20 to 70°C
• Low Jitter: 0.15ps RMS Typical
• Differential LVPECL or LVDS outputs
• Tri-State Enable/Disable on Pad 2
• Tape and Reel Packaging
• RoHS Compliant / Lead Free

Package Characteristics
Package Hermetically sealed ceramic package and metal cover
Environmental Characteristics
Vibration: Vibration per Mil Std 883E Method 2007.3 Test Condition A.
Shock: Mechanical Shock per Mil Std 883E Method 2002.4 Test Condition B.
Soldering Process: RoHS compliant lead free. See soldering profile on page 4.
Notes:
1. Includes calibration @ 25°C, frequency stability vs. change in temperature, supply voltage and load variations, shock and vibration and 20 years aging.
2. When the oscillator is disabled the outputs go to tri-state level (high impedance) which floats to V
OL
. Outputs are enabled with no connection on E/D pad.
3. LVPECL outputs must be terminated into 50 ohms to Vdd – 2V or Thevenin equivalent.
4. Vod is measured with a 100 ohm resistor between the true and the complementary outputs.
