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 slew rate control
- 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
Data Interface, various device functions, such as individual
clock output buffers are individually enabled or disabled. The
registers associated with the Serial Data Interface initialize to
Pin No.
