Integrated Circuit Systems, Inc. ICS844004I-04 FEMTOCLOCKS CRYSTAL/LVCMOS-TOLVDS FREQUENCY SYNTHESIZER The ICS844004I-04 is a 4 output LVDS Synthesizer optimized to generate clock HiPerClockS frequencies for a variety of high performance applications and is a member of the HiPerClocksTM family of high performance clock solutions from ICS. This device can select its input reference clock from either a crystal input or a single- ended clock signal. It can be configured to generate 4 outputs with individually selectable divide-by-one or divide-by-four function via the 4 frequency select pins F_SEL[3:0] . The ICS844004I-04 uses ICS’ 3rd generation low phase noise VCO technology and can achieve 1ps or lower typical rms phase jitter. This ensures that it will easily meet clocking requirements for SDH STM-1/ STM-4/STM-16 and SONET OC-3/OC12/OC-48 . This device is suitable for multi-rate and multiple port line card applications. The ICS844004I-04 is conveniently packaged in a small 24-pin TSSOP package. • Four LVDS outputs • Selectable crystal oscillator interface or LVCMOS/LVTTL single-ended input • Supports the following applications SONET/SDH, SATA, or 10Gb Ethernet • Output frequency range 140MHz - 170MHz, 560MHz - 680MHz • VCO range 560MHz - 680MHz • Crystal oscillator and CLK range 17.5MHz - 21.25MHz • RMS phase jitter 622.08MHz output, using a 19.44MHz crystal 12kHz - 20MHz 0.71ps typical • RMS phase jitter 156.25MHz output, using a 19.53125MHz crystal 1.875MHz - 20MHz 0.51ps typical • RMS phase jitter 155.52MHz output, using a 19.44MHz crystal 12kHz - 5MHz 0.75ps typical • Full 3.3V supply mode • -40°C to 85°C ambient operating temperature • Available in both standard and lead-free RoHS compliant packages BLOCK DIAGRAM PIN ASSIGNMENT XTAL_IN OSC 0 XTAL_OUT Phase CLK Pulldown Detector TABLE ORDERING INFORMATION Part/Order Number Marking Package Shipping Packaging Temperature 844004AGI-04 ICS844004AI04 24 Lead TSSOP tube -40°C to 85°C 844004AGI-04T ICS844004AI04 24 Lead TSSOP 2500 tape & reel -40°C to 85°C S84004AGI-04LF ICS44004AI04L 24 Lead "Lead-Free" TSSOP tube -40°C to 85°C 844004AGI-04LFT ICS44004AI04L 24 Lead "Lead-Free" TSSOP 2500 tape & reel -40°C to 85°C NOTE Parts that are ordered with an "LF" suffix to the part number are the Pb-Free configuration and are RoHS compliant.
