FEMTOCLOCKS CRYSTAL-TO-LVCMOS/LVTTL FREQUENCY SYNTHESIZER ICS840304I ICS840304I is an optimized PCI-X and PCI-e clock generator and a member of the HiperClocks family HiPerClockS of high performance clock solutions from IDT. The ICS840304I uses a 25MHz parallel crystal to generate 33.33MHz to 133.33MHz clock signals, replacing solutions requiring multiple oscillator and fanout buffer solutions. The device supports 1% downspread spread spectrum clocking. The ICS840304I has excellent phase jitter <1ps rms over integration range of 1.5MHz - 22MHz. Designed for Backplane, networking and industrial applications, the ICS840304I can also drive the high-speed PCI-X and PCI-e SerDes clock inputs of communication processors, DSPs, switches and bridges. • Four LVCMOS/LVTTL outputs, typical output impedance One REF_OUT LVCMOS/LVTTL clock output • Selectable crystal oscillator interface, 25MHz, 18pF parallel resonant crystal or LVCMOS/LVTTL single-ended clock input • Support the following output frequencies 33.33MHz, 66.67MHz, 100MHz or 133.33MHz • VCO 400MHz • PLL and N divider bypass and output enable • RMS phase jitter using a 25MHz crystal, 1.5MHz - 22MHz 0.46ps typical 3.3V • Supports SSC, 1% downspread • Full 3.3V and 2.5V supply modes • -40°C to 85°C ambient operating temperature • Available in both standard RoHS 5 and lead-free RoHS 6 packages BLOCK DIAGRAM BYPASS Pulldown XTAL_IN XTAL_OUT OSC 0 REF_IN Pulldown REF_SEL Pulldown SSC Pulldown nOE Pulldown F_SEL[1:0] Pulldown 2 nREF_OE Pullup FemtoClock VCO = 400MHz M = ÷16 Q0 Q1 Q2 Q3 REF_OUT PIN ASSIGNMENT VDD 1 XTAL_IN 2 XTAL_OUT 3 TABLE ORDERING INFORMATION Part/Order Number Marking Package Shipping Packaging Temperature ICS840304BGI ICS840304BGI 24 Lead TSSOP tube -40°C to 85°C ICS840304BGIT ICS840304BGI 24 Lead TSSOP 2500 tape & reel -40°C to 85°C ICS840304BGILF ICS840304BGIL 24 Lead "Lead-Free" TSSOP tube -40°C to 85°C ICS840304BGILFT ICS840304BGIL 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.

FEMTOCLOCKS CRYSTAL-TO-LVCMOS/LVTTL FREQUENCY SYNTHESIZER

ICS840304I

ICS840304I is an optimized PCI-X and PCI-e clock
generator and a member of the HiperClocks family

HiPerClockS of high performance clock solutions from IDT. The

ICS840304I uses a 25MHz parallel crystal to
generate 33.33MHz to 133.33MHz clock signals,
replacing solutions requiring multiple oscillator and fanout buffer
solutions. The device supports 1% downspread spread spectrum
clocking. The ICS840304I has excellent phase jitter <1ps rms
over integration range of 1.5MHz - 22MHz. Designed for

Backplane, networking and industrial applications, the

ICS840304I can also drive the high-speed PCI-X and PCI-e

SerDes clock inputs of communication processors, DSPs,
switches and bridges.
• Four LVCMOS/LVTTL outputs, typical output impedance One REF_OUT LVCMOS/LVTTL clock output
• Selectable crystal oscillator interface, 25MHz, 18pF parallel resonant crystal or LVCMOS/LVTTL single-ended clock input
• Support the following output frequencies 33.33MHz, 66.67MHz, 100MHz or 133.33MHz
• VCO 400MHz
• PLL and N divider bypass and output enable
• RMS phase jitter using a 25MHz crystal, 1.5MHz - 22MHz 0.46ps typical 3.3V
