TI enters JESD204B market

Texas Instruments introduced a pair of devices supporting the JEDEC JESD204B serial interface standard for data converters.
The ADS42JB69 is claimed to be the industry's first dual-channel, 16-bit analog-to-digital converter (ADC) featuring the JESD204B interface and is also the fastest at 250 MSPS. The LMK04828 is a high-performance clock jitter cleaner and is the first to support JESD204B clocking.

For designs requiring a traditional parallel interface, the company also introduced the ADS42LB69, ta fast dual, 16-bit ADC at 250 MSPS featuring an LVDS interface.

JESD204B is an industry-standard serial communications link that simplifies the digital data interface between data converters and other devices, such as FPGAs, DSPs and ASICs. The standard reduces the routing between devices, slashing input/output and board space requirements for applications, such as wireless communications, test and measurement, and defense and aerospace.

The ADS42JB69 maximizes flexibility in system design, because it is the only 16-bit ADC incorporating all three JESD204B subclasses, 0, 1 and 2, allowing multi-device synchronization between data converters. The ADS42JB69 also supports the new JESD204B standard for deterministic latency, which provides fixed transmission delay with or without the use of an external timing signal. The device is also compatible with the existing JESD204A standard.

Availability, packaging and pricing

Samples of the 16-bit ADS42JB69 (JESD204B) and ADS42LB69 (LVDS), and 14-bit ADS42JB49 (JESD204B) and ADS42LB49 (LVDS) are all available 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 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.
