描述
The 83908-02 is a low-skew, high-performance 1-to-8 crystal oscillator/crystal-to-LVCMOS fanout buffer. The 83908-02 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.
Guaranteed output and part-to-part skew characteristics make the 83908-02 ideal for those applications demanding well-defined performance and repeatability.
特性
- Eight LVCMOS/LVTTL outputs, 19Ω typical output impedance at VDD = VDDO = 3.3V
- Two crystal oscillator input pairs
One LVCMOS/LVTTL clock input - Crystal input frequency range: 10MHz to 40MHz
- Output frequency: 200MHz (maximum)
- Output skew: 70ps (maximum) at VDD = VDDO = 3.3V
- Part-to-part skew: 700ps (maximum) at VDD = VDDO = 3.3V
- RMS phase jitter at 25MHz output, using a 25MHz crystal,
(12kHz – 10MHz): 0.39ps (typical) at VDD = VDDO = 3.3V - RMS phase noise at 25MHz
