ZL30237 Description
9 3.0 Application Example . 13 4.0 Functional Description . 14 4.1 Frequency Synthesis Engine.
ZL30237 Key Features
- Generates clock signals at power-up per user defined custom OTP (One Time Programmable) configuration
- Operates from a single crystal resonator, clock oscillator or voltage controlled oscillator
- Two independently programmable Numerically Controlled Oscillators (NCOs) generate any clock rate from 1 kHz to 750 MHz
- NCOs generate clocks with jitter below 0.7 ps RMS for 10 G PHYs
- Frequency of each synthesizers can be fine tuned up to +/-0.5% by corresponding fine frequency adjustment circuit with r
- Fine frequency adjustment circuit dynamically configurable via SPI/I2C interface
- Supports programmable frequency offsets for clock margining
- Eight LVPECL outputs; max rate 750 MHz
- Four LVCMOS outputs; max rate 177.5 MHz
ZL30237 Applications
- Timing for NPUs, FPGAs, Ethernet switches and
- Timing for 10 Gigabit CDRs, Rapid-IO, PCIe
