DESCRIPTION

Two Programmable Control Inputs [S0/S1,

A0/A1] for User-Defined Control Signals

The CDCE706 is one of the smallest and most

powerful PLL synthesizer/multiplier/dividers available

today. Despite its small physical outline, the

CDCE706 is very flexible. It has the capability to

produce an almost independent output frequency

from a given input frequency.

Six LVCMOS Outputs With Output Frequencies

up to 300 MHz

LVCMOS Outputs Can Be Programmed for

Complementary Signals

Free Selectable Output Frequency via

Programmable Output Switching Matrix [6×6]

Including 7-Bit Post-Divider for Each Output

The input frequency can be derived from an

LVCMOS, differential input clock, or single crystal.

The appropriate input waveform can be selected via

the SMBus data interface controller.

•

PLL Loop Filter Components Integrated

Low Period Jitter (Typically 60 ps)

To achieve an independent output frequency, the

reference divider M and the feedback divider N for

each PLL can be set to values from 1 to 511 for the

M-divider and from 1 to 4095 for the N-divider. The

PLL-VCO (voltage controlled oscillator) frequency

then is routed from the programmable output

switching matrix to any of the six outputs. The

switching matrix includes an additional 7-bit

post-divider (1 to 127) and an inverting logic for each

output.

Features Spread-Spectrum Clocking (SSC) for

Lowering System EMI

•

Programmable Output Slew-Rate Control

(SRC) for Lowering System EMI

•

3.3-V Device Power Supply

Industrial Temperature Range –40°C to 85°C

Development and Programming Kit for Easy

PLL Design and Programming (TI ClockPro

Software)

The deep M/N divider ratio allows the generation of

zero-ppm clocks from any reference input frequency

(e.g., 27 MHz).

•

Packaged in 20-Pin TSSOP

The CDCE706 includes three PLLs; of those, one

supports spread-spectrum clocking (SSC). PLL1,

PLL2, and PLL3 are designed for frequencies up to

300 MHz and optimized for zero-ppm applications

with wide divider factors.
