DESCRIPTION

The CDCM61004 is a highly versatile, low-jitter

frequency synthesizer that can generate four low-jitter

clock outputs, selectable between low-voltage

positive emitter coupled logic (LVPECL), low-voltage

differential signaling (LVDS), or low-voltage

•

Supports Common LVCMOS Output

Frequencies:

–

62.5 MHz, 74.25 MHz, 75 MHz, 77.76 MHz,

100 MHz, 106.25 MHz, 125 MHz, 150 MHz,

155.52 MHz, 156.25 MHz, 159.375 MHz,

187.5 MHz, 200 MHz, 212.5 MHz, 250 MHz

complementary

metal

oxide

semiconductor

(LVCMOS) outputs, from a low-frequency crystal for a

variety of wireline and data communication

applications. The CDCM61004 features an onboard

PLL that can be easily configured solely through

control pins. The overall output random jitter

performance is less than 1ps, RMS (from 10 kHz to

20 MHz), making this device a perfect choice for use

in demanding applications such as SONET, Ethernet,

Fibre Channel, and SAN. The CDCM61004 is

available in a small, 32-pin, 5-mm × 5-mm QFN

package.

Output Frequency Range: 43.75 MHz to

683.264 MHz (See Table 3)

•

Internal PLL Loop Bandwidth: 400 kHz

High-Performance PLL Core:

–

Phase Noise typically at –146 dBc/Hz at

5-MHz Offset for 625-MHz LVPECL Output

–

Random Jitter typically at 0.509 ps, RMS

(10 kHz to 20 MHz) for 625-MHz LVPECL

Output

•

Output Duty Cycle Corrected to 50% (± 5%)
