32-QFN Pin Definitions
EProClock Programmable Technology
EProClock is the world’s first non-volatile programmable
clock. The EProClock technology allows board designer to
promptly achieve optimum compliance and clock signal
integrity; historically, attainable typically through device and/or
board redesigns.
EProClock technology can be configured through SMBus or
hard coded.
Features:
- > 4000 bits of configurations
- Can be configured through SMBus or hard coded
- Custom frequency sets
- Differential skew control on true or compliment or both
- Differential duty cycle control on true or compliment or both
- Differential amplitude control
- Differential and single-ended slew rate control
- Program Internal or External series resistor on single-ended
clocks
- Program different spread profiles and modulation rates
Serial Data Interface
To enhance the flexibility and function of the clock synthesizer,
a two-signal serial interface is provided. Through the Serial
Pin No.
