PRELIMINARY

CRYSTAL-TO-0.7V DIFFERENTIAL HCSL/

LVCMOS FREQUENCY SYNTHESIZER

ICS841S012I

ENERAL

ESCRIPTION

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 ±0.25% center-spread, and -0.5% 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.

EATURES

• 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: ±0.25% center-spread and

-0.5% 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

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 character istic 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 high-

speed clock inputs of communication processors, DSPs,

switches and bridges.
