ZL30237
ZL30237 is Dual Channel Universal NCO Clock Generator manufactured by Microsemi.
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 k Hz 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 resolution of 0.24 ppb
- 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
