ICS83908I-02 Datasheet, PDF (1/16 Pages) Integrated Device Technology – LOW SKEW, 1-TO-8 CRYSTAL-TO-LVCMOS FANOUT BUFFER

PRELIMINARY
LOW SKEW, 1-TO-8 CRYSTAL-TO-LVCMOS
FANOUT BUFFER
ICS83908I-02
GENERAL DESCRIPTION
The ICS83908I-02 is a low skew, high performance
ICS
1-to-8 Crystal Oscillator/3.3V LVCMOS-to-3.3V
HiPerClockS™ _{LVCMOS fanout buffer and a member of the}
HiPerClockS™ family of High Performance Clock
Solutions from IDT. The ICS83908I-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.
FEATURES
• Eight LVCMOS/LVTTL outputs
(19Ω typical output impedance)
• Two Crystal oscillator input pairs
One LVCMOS/LVTTL clock input
• Crystal input frequencry range: 10MHz - 40MHz
• Output frequency: 200MHz (typical) CLK0
• Output Skew: TBD
Guaranteed output and part-to-part skew characteristics make
the ICS83908I-02 ideal for those applications demanding well
defined performance and repeatability.
• Part to Part Skew: TBD
• RMS phase jitter @ 25MHz (100Hz - 1MHz):
0.22ps (typical) V_DD = V_DDO = 3.3V
