For synchronization, clock and data recovery, and jitter attenuation in network elements, jitter attenuators provide a fully integrated clock/PLL timing solution.
There are numerous variants with multiple selectable inputs and up to four outputs with frequencies greater than 1.0GHz available in LVPECL, LVDS, SINE, or CMOS. Jitter is less than 0.2ps when measured over the OC-48 bandwidth (RMS 12KHz to 20MHz).
Many physical layer interconnect devices advise using jitter attenuators because they go beyond the jitter specifications of the majority of communication specifications.
De-jittering devices Our jitter attenuators offer the greatest jitter cleaning available thanks to our DSPLL and MultiSynth technology. Because they can produce any combination of output frequencies from any input frequency, they make clock synthesis easier and require fewer timing components overall.
The Global Jitter Attenuators market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
The LMK61E2 ultra-low jitter programmable oscillator from Texas Instruments comes with an embedded EEPROM.
Texas Instruments’ LMK61E2 ultra-low jitter programmable oscillator is a fractional-N frequency synthesizer with integrated VCO that provides routinely used reference clocks. The outputs can be set up as LVDS, HCSL, or LVPECL.
The system has an on-chip EEPROM that self-starts and is pre-configured to produce 156.25 MHz LVPECL output. I2C serial interface allows for complete in-system programming of the device registers and EEPROM settings.
The cost and complexity of the power delivery network are decreased thanks to internal power conditioning’s outstanding power supply ripple rejection (PSRR).
One 3.3 V 5% supply is all that the device needs to run. The tool offers choices for both fine and coarse frequency margining.Through I2C serial interface to provide system design verification tests (DVT), including system timing margin testing and standard compliance.
