JESD204B Data Converter Interfaces

Industry's Fastest Dual 16-bit ADC and First Clock Jitter Cleaner Supporting JESD204B Data Converter Interfaces

ACE Award 2013 FinalistTexas Instruments' ADS42JB69 dual 16-bit 250 MSPS ADC and LMK04828 high performance clock jitter cleaner offer a simple way for system designers to achieve JESD204B serial interface compliance, while delivering unmatched performance and reducing BOM cost. The LMK04828 provides ultra-low-jitter and phase noise and generates the JESD204B system timing reference signal (SYSREF) required for multi-device synchronization.


ADS42JB69 dual 16-bit 250 MSPS ADC with JESD204B interface:

Features and Benefits

  • Highest performance:
    • SFDR performance of 89 dBc at 170 MHz IF is up to 9 dB better than the competition
    • SNR performance of up to 74.9 dBFS at 170 MHz IF
  • Easy analog input interface: High-impedance analog input buffer with programmable full-scale range simplifies input filter and drive circuitry and increases performance uniformity and device-to-device repeatability across the analog input frequency range
  • Lowest power consumption: Consumes 775 mW/channel
  • Most comprehensive JESD204B implementation: The industry's only 16-bit ADC to support JESD204B subclass 0, 1, and 2
  

LMK04828 high performance clock jitter cleaner for JESD204B interface:

Features and Benefits

  • Lowest jitter: Less than 100 fs RMS jitter (10 kHz to 20 MHz) at 245.76 MHz using a low-noise VCXO module
  • Performance and functional integration: Reduces clock architecture complexity while providing options to maximize system performance
  • Greater flexibility:
    • Dual VCO cores operate at 2.5 GHz or 2.9 GHz, with 14 programmable clock outputs in LVDS, LVPECL, or HSDS interface options
    • Holdover; switchover; multiple inputs; odd/even dividers; and programmable digital delay, analog delay, and zero delay; and the ability to output additional high speed clocks
  • Generates JESD204B subclass 1 SYSREF: Half the outputs are configurable as either device clocks or JESD204B SYSREF companion signals to device clocks for all subsystem components requiring timing synchronization
