General Description
The IDT8L3010I 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 IDT8L3010I 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
Output skew: 50ps (maximum) @ 3.3V/3.3V
Additive RMS phase jitter: 0.24ps (typical) @ 3.3V/3.3V
Synchronous output enable to avoid clock glitch
Power supply modes:
Core / Output
3.3V / 3.3V
2.5V / 2.5V
3.3V / 2.5V
3.3V / 1.8V
3.3V / 1.5V
2.5V / 1.8V
2.5V / 1.5V
5V input tolerance
-40°C to 85°C ambient operating temperature
Available in lead-free (RoHS 6) package
