Richardson RFPD Introduces Two New DACs For CATV From ADI

AD9119 and AD9129

High dynamic range and bandwidth enable multicarrier generation up to 4.2 GHz

Richardson RFPD, Inc. today announces immediate availability and full design support capabilities for two new digital-to-analog converters (DACs) from Analog Devices, Inc. (ADI).

The AD9119 and AD9129 are high performance, 11-/14-bit RF DACs that support data rates up to 2.8 GSPS. The devices are based on a quad-switch architecture that enables dual-edge clocking operation, effectively increasing the DAC update rate to 5.6 GSPS when configured for Mix-Mode or 2×interpolation. The high dynamic range and signal reconstruction bandwidth support RF signal synthesis of up to 4.2 GHz, making them ideally suited for a range of CATV, wireless infrastructure, instrumentation, automatic test equipment (ATE), radar, and jammer applications.

The new DACs feature a dual-port interface with double data rate (DDR) low-voltage differential signaling (LVDS) data receivers that supports 2800 MSPS maximum conversion rate and simplifies system integration. The devices are manufactured on a complementary metal-oxide-semiconductor (CMOS) process, and an ADI-proprietary switching technique enhances dynamic performance.

Additional key features of the AD9119 and AD9129 include:

  • Direct RF synthesis at 2.8 GSPS data rate
    • DC to 1.4 GHz in baseband mode
    • DC to 1.0 GHz in 2× interpolation mode
    • 1.4 GHz to 4.2 GHz in Mix-Mode
  • Bypassable 2× interpolation
  • Supports DOCSIS 3.0 wideband ACLR/harmonic performance
  • 8 QAM carriers: ACLR > 65 dBc
  • Industry-leading single/multicarrier IF or RF synthesis
    • 4-carrier W-CDMA ACLR at 2457.6 MSPS
      • fOUT = 900 MHz, ACLR = 71 dBc (baseband mode)
      • fOUT = 2100 MHz, ACLR = 68 dBc (Mix-Mode)
      • fOUT = 2700 MHz, ACLR = 67 dBc (Mix-Mode)
  • Dual-port LVDS and DHSTL data interface
    • Up to 1.4 GSPS operation
    • Source synchronous DDR clocking with parity bit
  • Low power: 1.0 W at 2.8 GSPS (1.3 W at 5.6 GSPS)

The AD9119 and AD9129 are part of ADI's Select Products for Q2, 2013.

The devices are in stock and available for immediate delivery. To find more information, or to purchase the devices today on the Richardson RFPD website, please visit the AD9119 and AD9129 webpage.
