Crystal or Differential-to-LVCMOS/
LVTTL Clock Buffer
8L30110
Datasheet
Description
The 8L30110 is a low skew, 1-to-10 LVCMOS / LVTTL Fanout
Buffer. The low impedance LVCMOS/LVTTL outputs are designed
to drive 50 series or parallel terminated transmission lines.
The 8L30110 is characterized at full 3.3V and 2.5V, mixed
3.3V/2.5V, 3.3V/1.8V, 3.3V/1.5V, 2.5V/1.8V and 2.5V/1.5V output
operating supply modes. The input clock is selected from two
differential clock inputs or a crystal input. The differential input can
be wired to accept a single-ended input. The internal oscillator
circuit is automatically disabled if the crystal input is not selected.
Features
• Ten LVCMOS / LVTTL outputs up to 200MHz
• Differential input pair can accept the following differential input
levels: LVPECL, LVDS, HCSL
• Crystal Oscillator Interface
• Crystal input frequency range: 8MHz to 50MHz
• Output skew: 63ps (typical)
• Additive RMS phase jitter: 22fs (typical)
• Power supply modes:
