TI device pair supports JEDEC JESD204B

-November 02, 2012

In support of the JEDEC JESD204B serial interface standard that defines the serial communications link between data converters and other devices, TI unveiled the ADS42JB69 first and fastest dual-channel, 16-bit ADC featuring the JESD204B interface at 250 MSPS. The LMK04828 is, according to TI, the industry’s highest-performance clock jitter cleaner and first to support JESD204B clocking. In combo, the devices deliver the highest system-level performance for high-speed systems.

In addition, for designs requiring a traditional parallel interface, the ADS42LB69 is the industry’s fastest dual, 16-bit ADC at 260 MSPS featuring an LVDS interface.

Features include:

The LMK04828 clock jitter cleaner features:

JESD204B significantly reduces the number of lanes required for data interface and the embedded output data clock eliminates line buss matching. Applications include wireless, test and measurement and defense and aerospace.

The combination of the devices for wireless infrastructure and software defined radio (SDR) include improved dynamic range and wideband sampling reduces interference, providing greater signal integrity. Low power consumption and high performances maximizes receiver sensitivity in multicarrier GSM, UMTS and LTE base stations. Benefits for portable spectrum analyzers and communications test equipment include high SNR and dynamic range increase resolution and receiver sensitivity, while low power consumption extends battery life.

An ADC evaluation platform enables a quick design start. The following evaluation modules (EVMs) are available to speed development with the new 16- and 14-bit, 250 MSPS ADCs:

 

  • 16-bit ADS42JB69SEK and 14-bit ADS42JB49SEK with JESD204B interface for US$999
  • 16-bit  ADS42LB69EVM and 14-bit ADS42LB49EVM with LVDS interface for US$399

 

The EVMs connect to the TSW1400EVM high-speed data capture and pattern generation platform  for data analysis, as well as FPGA development platforms from Altera and Xilinx.

 

  • The LMK04828EVAL module can be purchased today for US$499.

 

Samples all available today in a 9-mm by 9-mm QFN package. Production quantities are expected in 2Q 2013 with 1,000-unit budgetary pricing of US$185 for the ADS42JB69 and ADS42LB69 and US$125 for the ADS42JB49 and ADS42LB49.

Samples of the LMK04828 are available today in a 9-mm by 9-mm QFN package. Production quantities will be available in 1Q 2013 for a suggested retail price of US$11.20 in 1,000-unit quantities. For systems requiring VCOs operating at 1.9 GHz or 2.5 GHz, the LMK04826 will be sampling in early 1Q 2013 with production quantities available later in the quarter for US$11.20 in 1,000-unit quantities.
