FS_OUT–

FS_OUT+

OMULTI

Frame Sync Output.

Differential 8 kHz frame sync output or fifth high-speed clock

output with a frequency specified by FRQSEL and FRQTBL.

Output signal format is selected by SFOUT pins. Detailed oper-

ations and timing characteristics for this pin may be found in

the Any-Rate Precision Clock Family Reference Manual. Out-

put is differential for LVPECL, LVDS, and CML compatible

modes. For CMOS format, both output pins drive identical sin-

gle-ended clock outputs.

CKOUT2+

CKOUT2–

OMULTI

Clock Output 2.

Differential output clock with a frequency specified by FRQSEL

and FRQTBL. Output signal format is selected by SFOUT pins.

Output is differential for LVPECL, LVDS, and CML compatible

modes. For CMOS format, both output pins drive identical sin-

gle-ended clock outputs.

CKOUT4–

CKOUT4+

OMULTI

Clock Output 4.

Differential output clock with a frequency specified by FRQSEL

and FRQTBL settings. Output signal format is selected by

SFOUT pins. Output is differential for LVPECL, LVDS, and

CML compatible modes. For CMOS format, both output pins

drive identical single-ended clock outputs.

GND PAD

GND

Supply

Ground Pad.

The ground pad must provide a low thermal and electrical

impedance to a ground plane.
