| DATA SHEET FEMTOCLOCKICnSitrecg uriatteCd RYSTAL-TOGENERATOR Systems, Inc. LVDS CLOFECMKTOCLOCKS ICS84I4C0S5814I4051I CRYSTAL-TO- LVDS CLOCK GENERATOR The ICS844051I is a Gigabit Ethernet Clock Generator and a member of the HiPerClocksTM HiPerClockS family of high performance devices from ICS. The ICS844051I can synthesize 10 Gigabit Ethernet, SONET, or Serial ATA reference clock frequencies with the appropriate choice of crystal and output divider. The ICS844051I has excellent phase jitter perfor- mance and is packaged in a small 8-pin TSSOP, making it ideal for use in systems with limited board space. • One Differential LVDS output • Crystal oscillator interface designed for 18pF parallel resonant crystals 18.125MHz - 23.4375MHz • Output frequency range 145MHz - 187.5MHz and 72.5MHz - 93.75MHz • VCO range 580MHz - 750MHz • RMS phase jitter 1.875MHz - 20MHz 0.45ps typical • 3.3V or 2.5V operating supply • -40°C to 85°C ambient operating temperature • Available in both standard and lead-free RoHS-compliant packages FREQUENCY TABLE Inputs Crystal Frequency MHz FREQ_SEL 0 1 0 1 0 1 0 1 Output Frequency MHz 150 75 BLOCK DIAGRAM FREQ_SEL Pulldown XTAL_IN XTAL_OUT Phase Detector ÷32 fixed 0 ÷4 default 1 ÷8 PIN ASSIGNMENT VDDA 1 GND 2 Q XTAL_OUT 3 XTAL_IN 4 8 VDD 7Q 6 nQ 5 FREQ_SEL ICS844051I 8-Lead TSSOP 4.40mm x 3.0mm x 0.925mm TABLE ORDERING INFORMATION Part/Order Number Marking Package Shipping Packaging Temperature ICS844051CGI 451CI 8 Lead TSSOP tube -40°C to 85°C ICS844051CGIT 451CI 8 Lead TSSOP 2500 tape & reel -40°C to 85°C ICS844051CGILF 8 Lead "Lead-Free" TSSOP tube -40°C to 85°C ICS844051CGILFT 8 Lead "Lead-Free" TSSOP 2500 tape & reel -40°C to 85°C NOTE Parts thar are ordered with an "LF" suffix to the part number are the Pb-Free configuraiton and are RoHS compliant.
