ming/CMOS-Clock-Generators

? Generates up to 8 non-integer-related

frequencies from 2.5 kHz to 200 MHz

? Exact frequency synthesis at each

output (0 ppm error)

? Highly linear VCXO gain (kv)

? Glitchless frequency changes

? Low output period jitter: < 70 ps pp, typ

? Configurable Spread Spectrum

selectable at each output

? User-configurable control pins:

??Output Enable (OEB_0/1/2)

??Power Down (PDN)

??Frequency Select (FS_0/1)

??Spread Spectrum Enable (SSEN)

? Supports static phase offset

? Rise/fall time control

? Operates from a low-cost, fixed

frequency AT-cut, non-pullable

crystal: 25 or 27 MHz

? Separate voltage supply pins provide

level translation:

??Core VDD: 2.5 V or 3.3 V

??Output VDDO: 1.8 V, 2.5 V, or 3.3 V

? Excellent PSRR eliminates external

power supply filtering

? Very low power consumption

(25 mA, core, typ)

? Available in three packages types:

??10-MSOP: 3 outputs

??16-QFN (3x3 mm): 4 output

??20-QFN (4x4 mm): 8 output

? PCIE Gen 1 compliant

? Supports HCSL compatible swing
