描述
The 83904I-02 is a low-skew, high-performance 1-to-4 crystal-to-LVCMOS fanout buffer. The 83904I-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 83904I-02 ideal for those applications demanding well-defined performance and repeatability.
特性
- Four LVCMOS/LVTTL outputs, 19Ω output impedance at VDD = VDDO = 3.3V
- Two crystal oscillator input pairs LVCMOS/LVTTL clock input
- Crystal input frequency range: 12MHz to 38.88MHz
- Output frequency: 200MHz (maximum)
- Output skew: 40ps (maximum) at VDD = VDDO = 3.3V
- RMS phase jitter at 25MHz output, using a 25MHz crystal, (100Hz to 1MHz): 0.16ps (typical) at VDD = VDDO = 3.3V
- RMS phase noise at 25MHz
