8. Device Pinout by Part Number
The Si5338 is orderable in three different speed grades: Si5338A/D/G/K/N have a maximum output clock
frequency limit of 710 MHz. Si5338B/E/H/L/P have a maximum output clock frequency of 350 MHz. Si5338C/F/J/
M/Q have a maximum output clock frequency of 200 MHz.
Devices are also orderable according to the pin control functions available on Pins 3 and 4:
