CRYSTAL-TO-0.7V DIFFERENTIAL HCSL/ LVCMOS FREQUENCY SYNTHESIZER ICS841S012I The ICS841S012I is an optimized PCIe, sRIO and Gigabit Ethernet Frequency Synthesizer and a HiPerClockS member of HiperClock s family of high perfor- mance clock solutions from IDT. The ICS841S012I uses a 25MHz parallel resonant crystal to gener- ate 33.33MHz - 200MHz clock signals, replacing solutions requiring multiple oscillator and fanout buffer solution. The device supports center-spread, and down- spread clocking with two spread select pins SSC[1:0] . The VCO operates at frequency of 2GHz. The device has three output banks Bank A with two HCSL outputs, 100MHz 250MHz Bank B with seven 33.33MHz 200MHz LVCMOS/ LVTTL outputs and Bank C with one 33.33MHz 200MHz LVCMOS/LVTTL output. All Banks A, B and C have their own dedicated frequency select pins and can be independently set for the frequencies mentioned above. The low jitter characteristic of the ICS841S012I makes it an ideal clock source for PCIe, sRIO and Gigabit Ethernet applications. Designed for networking and industrial applications, the ICS841S012I can also drive the highspeed clock inputs of communication processors, DSPs, switches and bridges. • Two 0.7V differential HCSL outputs Bank A , configurable for PCIe 100MHz or 250MHz and sRIO 100MHz or 125MHz clock signals Eight LVCMOS/LVTTL outputs Banks B/C , 15Ω typical output impedance Two REF_OUT LVCMOS/LVTTL clock outputs, 20Ω typical output impedance • Selectable crystal oscillator interface, 25MHz, 18pF parallel resonant crystal or one LVCMOS/LVTTL single-ended reference clock input • Supports the following output frequencies HCSL Bank A 100MHz, 125MHz, 200MHz and 250MHz LVCMOS/LVTTL Bank B/C 33.33MHz, 50MHz, 66.67MHz, 100MHz, 125MHz, 133.33MHz, 166.67MHz and 200MHz • VCO 2GHz • Spread spectrum clock center-spread and down-spread • PLL bypass and output enable • RMS period jitter 15ps typical , QB outputs • Full 3.3V supply mode • -40°C to 85°C ambient operating temperature • Available in both standard RoHS 5 and lead-free RoHS 6 packages PIN ASSIGNMENT VDDOB QB6 GND QB5 VDDOB QB4 GND QB3 VDDOB QB2 GND QB1 QB0 VDDOB VDD REF_OUT0 REF_OUT1 GND REF_IN VDD REF_SEL XTAL_IN XTAL_OUT BYPASS REF_OE nMR VDD 56 55 54 53 52 51 50 49 48 47 46 45 44 43 ICS841S012I 56-Lead VFQFN 38 37 7 8mm x 8mm x 0.925mm 36 package body K Package 10 11 TABLE ORDERING INFORMATION Part/Order Number Marking Package Shipping Packaging Temperature 841S012BKI 56 lead VFQFN tray -40°C to 85°C 841S012BKIT 56 lead VFQFN 1000 tape & reel -40°C to 85°C 841S012BKILF ICS841S012BIL 56 lead "Lead-Free" VFQFN tray -40°C to 85°C 841S012BKILFT ICS841S012BIL 56 lead "Lead-Free" VFQFN 1000 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.

CRYSTAL-TO-0.7V DIFFERENTIAL HCSL/ LVCMOS FREQUENCY SYNTHESIZER

ICS841S012I

The ICS841S012I is an optimized PCIe, sRIO and

Gigabit Ethernet Frequency Synthesizer and a

HiPerClockS member of HiperClock s family of high perfor-
mance clock solutions from IDT. The ICS841S012I
uses a 25MHz parallel resonant crystal to gener-
ate 33.33MHz - 200MHz clock signals, replacing solutions
requiring multiple oscillator and fanout buffer solution. The
device supports center-spread, and down-
spread clocking with two spread select pins SSC[1:0] . The

VCO operates at frequency of 2GHz. The device has three
output banks Bank A with two HCSL outputs, 100MHz
250MHz Bank B with seven 33.33MHz 200MHz LVCMOS/

LVTTL outputs and Bank C with one 33.33MHz 200MHz

LVCMOS/LVTTL output.

All Banks A, B and C have their own dedicated frequency select pins and can be independently set for the frequencies mentioned above. The low jitter characteristic of the ICS841S012I makes it an ideal clock source for PCIe, sRIO and Gigabit Ethernet applications. Designed for networking and industrial applications, the ICS841S012I can also drive the highspeed clock inputs of communication processors, DSPs, switches and bridges.
