Silicon Labs’ differential + LVCMOS clock generators provide any rate, any output frequency synthesis. Any

combination of output frequencies can be generated exactly with 0 ppm error. Independent signal format and

VDDO options provide integrated level translation, supporting LVPECL/LVDS/HCSL/LVCMOS clock generation up

to 710 MHz with sub 1 ps rms phase jitter.

Si5338 FEATURES

• Generates any frequency on any output, from 160 kHz

to 350 MHz and select frequencies to 710 MHz

• Exact clock synthesis (0 ppm error)

• Crystal or clock input

• 4 differential outputs or 8 single-ended outputs

• Any format, on any output: LVPECL, LVDS, HCSL,

LVCMOS, HSTL, SSTL and CML

• Independent VDDO per output eliminates external

level translators (1.5, 1.8, 2.5, 3.3 V)

• Low phase jitter: 1 ps rms

• Excellent PSRR, no discrete components

• Spread spectrum clock generation

• User-definable control pins: Powerdown,

Output Enable, Frequency Select, Spread Select

• Factory-customizable clocks w/2 week lead times
