3.3-V HIGH PERFORMANCE RAD-TOLERANT CLASS V,
CLOCK SYNCHRONIZER AND JITTER CLEANER
Check for Samples: CDCM7005-SP
FEATURES
1
• High Performance LVPECL and LVCMOS PLL
Clock Synchronizer
• Two Reference Clock Inputs (Primary and
Secondary Clock) for Redundancy Support
With Manual or Automatic Selection
• Accepts LVCMOS Input Frequencies Up to
200 MHz
• VCXO_IN Clock is Synchronized to One of the
Two Reference Clocks
• VCXO_IN Frequencies Up to 2 GHz (LVPECL)
• Outputs Can Be a Combination of LVPECL and
LVCMOS (Up to Five Differential LVPECL
Outputs or Up to 10 LVCMOS Outputs)
• Output Frequency is Selectable by x1, /2, /3, /4,
/6, /8, /16 on Each Output Individually
• Efficient Jitter Cleaning From Low PLL Loop
Bandwidth
• Low Phase Noise PLL Core
• Programmable Phase Offset (PRI_REF and
SEC_REF to Outputs)
• Wide Charge Pump Current Range From
200 μA to 3 mA
• Dedicated Charge Pump Supply (VCC_CP) for
Wide Tuning Voltage Range VCOs
• Presets Charge Pump to VCC_CP/2 for Fast
Center Frequency Setting of VC(X)O
• Analog and Digital PLL Lock Indication
• Provides VBB Bias Voltage Output for Single-
Ended Input Signals (VCXO_IN)
• Frequency Hold Over Mode Improves Fail-Safe
Operation
• Power-Up Control Forces LVPECL Outputs to
3-State at V_CC < 1.5 V
