MILPITAS, CA May 11, 2015 Linear Technology Corporation announces the LTC2000A, a 16bit, 2.7Gsps digital toanalog converter (DAC) optimized for high end broadband wiredandwireless communications and radar applications. The LTC2000A offers exceptional spectral purity of 80dBc SFDR at 50MHz output and 72dBc SFDR at
1080MHz output to meet the most stringent requirements of high end applications. The device features better than
78dBc 2tone intermodulation distortion (IMD) from DC to 1080MHz output, low phase noise and a wide 2.1GHz
3dB output bandwidth. As a result, the LTC2000A enables broadband or high frequency direct RF synthesis in applications such as instrumentation, broadband communications, test equipment and cable TV DOCSIS CMTS.
The ±1V compliant outputs feature a 40mA full scale current which can be adjusted as low as10mA or as high as
60mA to suit the application. Data is transferred to the LTC2000A over a parallel LVDS interface port with transfer rates of up to 1.35Gsps using a 675MHz double data rate (DDR) data clock. Dual DDR ports are required to achieve the 2.7Gsps update rate while a single port can be used to operate at a lower 1.35Gsps update rate. At 2.7Gsps, the LTC2000A consumes 2.4W from dual 1.86V and 3.3V supplies, while at 1.35Gsps the device consumes just 1.4W. Designed for ease of use, the LTC2000A offers an internal pattern generator, LVDS loop out MUX, and junction temperature sensing to simplify system development and debug.
The LTC2000A is offered in 16bit, 14bit and 11bit versions in a RoHS compliant 9mm x 15mm BGA package. The LTC2000A is available in production today in commercial and industrial temperature grades, competitively priced, starting at $79.00 each for the LTC2000A16 in 1,000piece quantities. Demo boards and samples are available via the Linear Technology website www.linear.com/product/LTC2000A.
