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
