• Manufacturer Part Number: si5338b
• Description: I2c-programmable Any-rate , Any-output Quad Clock Generator
• Manufacturer: Silicon Laboratories

4. Device Pinout by Part Number
Si5338A/D/G/K have a maximum frequency limit of 700 MHz. Si5338B/E/H/L have a maximum frequency of
350 MHz. Si5338C/F/J/M have a maximum frequency of 200 MHz.
All Si5338 versions can have their reference clock come from a crystal oscillator or from a an onboard differential
input clock. In addition, all Si5338 versions can be used as a zero delay buffer by having CLK3A/B feed back to
pins 5 and 6.
TheSi5338A/B/C can be ordered to use a differential or a single-ended input clock and will have the I2C_LSB bit on
pin 4.
The Si5338D/E/F has the phase increment and decrement function available as pins. The Si5338G/H/J has the
frequency increment/decrement function available as pins. The Si5338K/L/M has the output enable (OEB) on pin 3
and the I2C_LSB on pin 4.
