DATA SHEET

General Description

Features

The ICS8430002 is a general purpose, high-

performance, fractional-n LVPECL frequency

synthesizer which can generate frequencies for a wide

variety of applications with output frequency step sizes

of <10ppm. The ICS8430002 has a 2:1 input

• 6-Bit Integer and 12-Bit Fractional Feedback Divider

• Dual differential 3.3V LVPECL outputs which can be set

HiPerClockS™

independently for either 3.3V or 2.5V

• 2:1 Input Mux:

One differential input

One crystal oscillator interface

Multiplexer from which either a crystal input or a differential input can

be selected. The differential input can be wired to accept

single-ended signals (see the applications section of this datasheet).

• PCLK, nPCLK pair can accept the following differential input

levels: LVPECL, CML, SSTL

Each of the differential LVPECL outputs has 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 outputs can run at 3.3V or 2.5V. The

ICS8430002 also supplies a buffered copy of the reference clock or

crystal frequency on the single-ended REF_OUT pin which can be

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

be programmed using either a serial or parallel programming

interface.

• Output frequency range: 30.625MHz to 640MHz

• Crystal input frequency range: 12MHz to 40MHz

• VCO range: 490MHz to 650MHz

• Parallel or serial interface for programming feedback divider and

output dividers

• Supply voltage modes:

Core/Outputs:

3.3V/3.3V

3.3V/2.5V

The device features a fractional feedback divider with a 6-bit integer

and 12-bit fractional value. The minimum step value of the feedback

divider is 1/4096.

• 0°C to 70°C ambient operating temperature

• Available in lead-free (RoHS 6) package
