Crystal-to-0.7V Differential HCSL/

LVCMOS Frequency Synthesizer

ICS841S012DI

DATA SHEET

GENERAL DESCRIPTION

FEATURES

The ICS841S012DI is an optimized PCIe, sRIO

and Gigabit Ethernet Frequency Synthesizer and

a member of HiperClocks™family of high perfor-

mance clock solutions from IDT. The

ICS841S012DI uses a 25MHz parallel resonant

• Tꢁo 0.7V differential HCSL outputs (Bank A), configurable for

PCIe (100MHz or 250MHz) and sRIO (100MHz or 125MHz)

clock signals

ICS

HiPerClockS™

Eight LVCMOS/LVTTL outputs (Banks B/C),

18Ω typical output impedance

crystal to generate 33.33MHz - 200MHz clock signals, replac-

ing multiple oscillators and fanout buffer solutions. The device

supports 0.25ꢀ center-spread, and -0.5ꢀ doꢁn-spread clock-

ing ꢁith tꢁo spread select pins (SSC[1:0]). The VCO operates

at a frequency of 2GHz. The device has three output banks:

Bank A ꢁith tꢁo 100MHz – 250MHz HCSL outputs; Bank B

ꢁith seven 33.33MHz – 200MHz LVCMOS/ LVTTL outputs; and

Bank C ꢁith one 33.33MHz – 200MHz LVCMOS/LVTTL output.

Tꢁo REF_OUT LVCMOS/LVTTL clock outputs,

23Ω typical output impedance

• Selectable crystal oscillator interface, 25MHz, 18pF parallel

resonant crystal or one LVCMOS/LVTTL single-ended

reference clock input

• Supports the folloꢁing 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

All Banks A, B and C have their oꢁn dedicated frequency

select pins and can be independently set for the frequencies

mentioned above. The loꢁ jitter characteristic of the

ICS841S012DI makes it an ideal clock source for PCIe, sRIO

and Gigabit Ethernet applications. Designed for netꢁorking and

industrial applications, the ICS841S012DI can also drive the

high-speed clock inputs of communication processors, DSPs,

sꢁitches and bridges.

• VCO: 2GHz

• Spread spectrum clock: 0.25ꢀ center-spread (typical) and

-0.6ꢀ doꢁn-spread (typical)

• PLL bypass and output enable

• RMS period jitter: 10ps (typical), QAx/nQAx outputs

• Full 3.3V supply mode

• -40°C to 85°C ambient operating temperature

• Available in lead-free (RoHS 6) package
