DESCRIPTION

•

Supports Common LVPECL/LVDS Output

Frequencies:

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

–

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,

311.04 MHz, 312.5 MHz, 622.08 MHz,

625 MHz

complementary

metal

oxide

semiconductor

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

LVCMOS input 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.

•

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

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

•
