8L30210
DATA SHEET
General Description
The 8L30210 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 8L30210 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: 10MHz to 40MHz
• Additive RMS phase jitter: 30fs (typical)
• Synchronous output enable to avoid clock glitch
• Power supply modes:
