SI5334 Datasheet, PDF (23/37 Pages) Silicon Laboratories – PIN-CONTROLLED ANY-FREQUENCY, ANY-OUTPUT QUAD CLOCK GENERATOR

Si5334
4. Device Pinout by Part Number
The Si5334 is orderable in three different speed grades: Si5334A/D/G/K have a maximum output clock frequency
limit of 710 MHz. Si5338B/E/H/L have a maximum output clock frequency of 350 MHz. Si5338C/F/J/M have a
maximum output clock frequency of 200 MHz.
Brief pin functions follow.
XTAL/CLKIN—crystal or one side of differential input clock
XTAL/CLKINB—crystal or one side of differential input clock
REFCLKSE—single-ended reference clock input
FDBKSE—single-ended feedback clock input
FDBK—differential feedback input
FDBKB—differential feedback input inverted
FINC—frequency increment pin
FDEC—frequency decrement pin
PINC—phase increment pin
PDEC—phase decrement pin
OEB—output enable low
See the four groupings below for the available pin control functions on pins 3, 4 and 12.
