ZL30237
Dual Channel Universal NCO Clock Generator
Overview
The ZL30237 Dual Channel Universal NCO Clock Generator, part of Microsemi's ClockCenter platform of Free Run Clock devices, delivers industry-leading synchronization performance for a range of applications. The free-run synchronization solution allows designers to replace multiple, costly components with a highly integrated, single-chip solution.
The ZL30237 integrates two independent numerically controlled oscillators (NCOs). Both NCOs are locked to the external crystal or oscillator and each can be used as a free running clock generator or be used to build a phase locked loop (PLL) where the phase detector and loop filter are provided externally. The device generates up to 12 clocks from a single crystal, allowing designers to replace numerous oscillators traditionally used to provide timing for various components with one chip.
Applications/Uses
- Timing for NPUs, FPGAs, Ethernet switches and PCIe switches
- Timing for 10 Gigabit CDRs, Rapid-IO, PCIe, Serial MII, Star Fabric, Fibre Channel, XAUI
- Processor clock, Processor bus clock, SDRAM clock, DDR clock
Key Features
-
- 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 720 MHz
- NCOs generate clocks with jitter below 0.7ps RMS for 10 G PHYs
- Frequency of each synthesizers can be fine tuned up to +/-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 720 MHz
- Four LVCMOS outputs; max rate 160 MHz
- Customer defined default configuration, including input/output frequencies, is available via OTP (One Time Programmable) memory
