Fanout Buffer

83908I-02

Data Sheet

GENERAL DESCRIPTION

FEATURES

• Eight LVCMOS/LVTTL outputs ,

The 83908I-02 is a low skew, high performance 1-to-8

Crystal Oscillator//Crystal-to-LVCMOS fanout buffer from

IDT. The 83908I-02 has selectable single-ended clock

or two crystal-oscillator inputs. There is an output enable to

disable the outputs by placing them into a high-impedance state.

19Ω typical output impedance @ V = V = 3.3V

DDO

• Two Crystal oscillator input pairs

One LVCMOS/LVTTL clock input

• Crystal input frequency range: 10MHz - 40MHz

• Output frequency: 200MHz (typical)

Guaranteed output and part-to-part skew characteristics make

the 83908I-02 ideal for those applications demanding well deﬁned

performance and repeatability.

• Output Skew: 70ps (maximum) @ V = V = 3.3V

DDO

• Part-to-part skew: 700ps (maximum) @ V = V = 3.3V

DDO

• RMS phase jitter @ 25MHz output using a 25MHz crystal

(12kHz - 10MHz): 0.39ps (typical) @ V = V = 3.3V
