GENERAL DESCRIPTION

FEATURES

The ICS843034-01 is a general purpose, low • Dual differential 3.3V LVPECL outputs which can be set

ICS

HiPerClockS™

phase noise LVPECL synthesizer which can

generate frequencies for a wide variety of

applications. The ICS843034-01 has a 4:1

input Multiplexer from which the following

inputs can be selected: 1 differential input, 1

independently for either 3.3V or 2.5V

• 4:1 Input Mux:

1 differential input

1 single-ended input

2 crystal oscillator interfaces

single-ended input, or one of two crystal oscillators,

thus making the device ideal for frequency translation or • CLK, nCLK pair can accept the following differential

generation. Each differential LVPECL output pair has an

output divider which can be independently set so that two

different frequencies can be generated. Additionally, each

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

• TEST_CLK accepts LVCMOS or LVTTL input levels

LVPECL output pair has a dedicated power supply pin so • Output frequency range: 30.625MHz to 640MHz

the outputs can run at 3.3V or 2.5V. The ICS843034-01

also supplies a buffered copy of the reference clock or

• Crystal input frequency range: 12MHz to 40MHz

crystal frequency on the single-ended REF_CLK pin which

can be enabled or disabled (disabled by default).The output

frequency can be programmed using either a serial or

parallel programming interface.

• VCO range: 490MHz to 640MHz

• Parallel or serial interface for programming feedback divider

and output dividers

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

(637kHz to 5MHz): 0.61ps (typical)

The ICS843034-01 has excellent <1ps phase jitter

performance over the 637kHz - 5MHz integration range, thus

making it suitable for use in Fibre Channel, SONET, and

Ethernet/1Gb Ethernet applications.

• Supply voltage modes:

LVPECL outputs (core/outputs):

3.3V/3.3V

Example applications include systems which must support

both FEC and non FEC rates. In 10Gb 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.

3.3V/2.5V

REF_CLK output (core/outputs):

3.3V/3.3V

3.3V/2.5V

• 0°C to 70°C ambient operating temperature

• Available in both standard and lead-free RoHS-compliant

packages
