PRELIMINARY

ICS84334

Integrated

Circuit

Systems, Inc.

MULTI-RATE LVPECL FREQUENCY

YNTHESIZER

GENERAL DESCRIPTION

FEATURES

The ICS84334 is a general purpose, low phase • Dual differential 3.3V LVPECL outputs which can be set

ICS

noise LVPECL synthesizer which can generate

frequencies for a wide variety of applications.The

ICS84334 has a 4:1 input Multiplexer from which

the following inputs can be selected: 1 differential

input, 1 single-ended input, or two crystal oscillators,

independently for either 3.3V or 2.5V

HiPerClockS™

• 4:1 Input Mux:

1 differential input

1 single-ended input

2 crystal oscillator interfaces

thus making the device ideal for frequency translation or

frequency generation.Each differential LVPECL output pair has • CLK, nCLK pair can accept the following differential

an output divider which can be independently set so that two

different frequencies can be generated. Additionally, each

LVPECL output pair has a dedicated power supply pin so the

input levels: LVPECL, LVDS, LVHSTL, HCSL, SSTL

• TEST_CLK accepts LVCMOS or LVTTL input levels

outputs can run at 3.3V or 2.5V.The ICS84334 also supplies a • Output frequency range: 31.25MHz to 700MHz

buffered copy of the reference clock or crystal frequency on the

single-ended REF_CLK pin which can be enabled or disabled

• Crystal input frequency range: 12MHz to 40MHz

(disabled by default).The output frequency can be programmed

using either a serial or parallel programming interface.

• VCO range: 500MHz to 700MHz

• Parallel or serial interface for programming feedback divider

and output dividers

The phase noise/phase jitter of the ICS84334 is excellent and

is expected to be in the 2-5ps rms range, thus making it

suitable for use in Fibre Channel, SONET, and Ethernet/1Gb

Ethernet applications.

• RMS phase jitter at 106.25MHz, using a 25.5MHz crystal

(637KHz to 5MHz): 2.31ps (typical)

Phase noise: 106.25MHz (typical), using a 25.5MHz crystal

Offset

Noise Power

Example applications include systems which must support both

FEC and non FEC rates. In 10 Gb Fibre Channel, for example,

you can use a 25.5MHz crystal to generate a 159.375MHz

reference clock, and then switch to a 20.544MHz crystal to

generate 164.355MHz for 66/64 FEC. Other applications could

include supporting both Ethernet frequencies and SONET

frequencies in an application. When Ethernet frequencies are

needed, a 25MHz crystal can be used and when SONET

frequencies are needed, the input MUX can be switched to select

a 38.88MHz Crystal.
