complementary

metal

oxide

semiconductor

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

LVCMOS input for a variety of wireline and data

communication applications. The CDCM61001

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

CDCM61001 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%)
