Low Skew, 1:6 Crystal Interface to

LVCMOS/ LVTTL Fanout Buffer

83905I

Datasheet

General Description

Features

The 83905I is a low skew, 1-to-6 LVCMOS / LVTTL Fanout Buffer.

The low impedance LVCMOS/LVTTL outputs are designed to

drive 50 series or parallel terminated transmission lines. The

effective fanout can be increased from 6 to 12 by utilizing the

ability of the outputs to drive two series terminated lines.

• Six LVCMOS / LVTTL outputs

• Outputs able to drive 12 series terminated lines

• Crystal Oscillator Interface

• Crystal input frequency range: 10MHz to 40MHz

• Output skew: 80ps (maximum)

The 83905I is characterized at full 3.3V, 2.5V, and 1.8V, mixed

3.3V/2.5V, 3.3V/1.8V and 2.5V/1.8V output operating supply

modes. Guaranteed output and part-to-part skew characteristics

along with the 1.8V output capabilities makes the 83905I ideal for

high performance, single ended applications that also require a

limited output voltage.

• RMS phase jitter @ 25MHz, (100Hz – 1MHz): 0.26ps (typical),

V_DD= V_DDO= 2.5V
