Featured ProductsClocksClock Synchronizer/Jitter CleanerCDCM7005-SPThe CDCM7005-SP high-performance, low-phase noise and low-skew clock synchronizersynchronizes a voltage-controlled crystal oscillator (VCXO) or voltage-controlledoscillator (VCO) frequency to one of two reference clocks. The CDCM7005-SP can lockto one of two reference clock inputs and supports frequency hold-over mode and fastfrequency locking for fail-safe and increased system redundancy.REF_SELPRI_REFSEC_REFCTRL_LECTRL_DATACTRL_CLKPDRESET orHOLDAutomaticLVCMOSREF_MUXVCReferenceClockFeedbackClockAVCCPECLtoLVCMOSFB_MUXMNVCC_CP10N 2 12LOCKPFDY0_MUXHOLDChargePumpCurrentReferenceLVCMOSLVPECLLVCMOSSTATUS_REF/PRI_SEC_CLKSTATUS_VCXO/I_REF_CPPLL_LOCKCP_OUTY0AY0BKey Features• Radiation performanceTID = 50 kRAD (Si)• Two reference clock inputs (primaryand secondary clock) for redundancysupport with manual or automaticselection• Accepts LVCMOS input frequencies upto 200 MHz• VCXO IN operating frequencies up to2.2 GHz (LVPECL)• Up to five differential LVPECL outputsor up to 10 LVCMOS outputs• Frequency is individually selectable oneach output• SPI-controllable device setting• 3.3-V power supply• High-performance 52-pin ceramicquad flat pack (HFG)• QML-V qualified,SMD 5962-0723001VXCVCXO_INVCXO_INVBBPECLINPUT/890 o90 oP16-DivPDividerVCC – 1.3VY3_MUXY2_MUXY1_MUXLVCMOSLVPECLLVCMOSLVCMOSLVPECLLVCMOSLVCMOSLVPECLLVCMOSLVCMOSY1AY1BY2AY2BY3AY3BY4AApplications• High-speed data acquisition andgeneration• MRI: magnetic resonance imaging• Orbital data aquisition• Satellite communications• Software defined radio (SDR)• Space-based imaging & surveillance• Spacecraft wireless infrastructure• Ultrasound system• X-ray: baggage scanner• X-ray: medicalY4_MUXLVPECLLVCMOSY4BGNDCDCM7005-SP functional block diagramGet more information: www.ti.com/product/CDCM7005-SPTexas Instruments Space Products Guide 2013 | 13
