VPLD54TCE is a 3.3V  
Voltage Controlled Crystal  
Oscillator (VCXO) with  
LVPECLDifferential outputs.  
The VPLD54TCE is designed  
for use with PLL systems in  
SONET/SDH systems  
requiring low jitter and tight  
stability.

PACKAGE CHARACTERISTICS  
TABLE 5.0  
Package  
Non-hermetic package consisting of an FR4 subst rate with grounded metal  
cover.  
PROCESS RECOMMENDATIONS  
Solder Reflow  
TABLE 6.0  
The component solder used internal to this device has a melting point of  
221°C. The peak temperature inside the device should be less than or  
equal to 220°C for a maximum of 10 seconds  
Wash  
Notes  
Ultrasonic cleaning is not recommended.  
ORDERING INFORMATION  
1.0  
Inclusive of calibration @ 25°C, frequency stability vs. temperature, supply and load variations, shock, vibration and aging  
for ten years. Control voltage (Vc) = 1.65 Vdc.  
Control voltage for (Fo) = 1.65 Vdc at 25°C. Positive Transfer Function.  
When oscillator is disabled the true output is in a low state (Vol) and the complementary output is in the high state (VoH)  
50 ohm termination into Vcc-2V or Thevein equivalent.
