Introducing the first of a new line of RF converters designed for GHz bandwidth applications such as 4G/5G multiband wireless communications base stations, multi-standard production test systems, and defense electronics. Based on 28 nm CMOS technology, these ADCs and DACs provide best-in-class bandwidth, power and dynamic range to cover the largest number of signal bands.

High Speed Converter Chip Designs

The AD9213 is a single-channel 12-bit 10.25GSPS RF ADC and includes an optional, independently programmable digital down-converter (DDC) block, optional/bypassable on-chip PLL, and JESD204B interface. The AD9213 enables digitization with >4GHz signal bandwidth while offering breakthrough parametric performance, with specific relevance to the aerospace and defense, instrumentation, and communications markets.

AD9213

The AD9172 is a high performance, dual, 16-bit digital-to-analog converter (DAC) that supports DAC sample rates to 12 GSPS. It features an 8-lane, 15 Gbps JESD204B data input port, a high performance on-chip DAC clock multiplier and digital signal processing capabilities targeted at single and multi-band direct-to-RF wireless applications.

The AD9208 is a dual, 14-bit 3.0 GSPS analog-to-digital converter (ADC). It has an on-chip buffer and a sample-and-hold circuit designed for low power, small size, and ease of use. This product is designed to support communications applications capable of sampling wide bandwidth analog signals of up to 5 GHz.

The AD9694 is a quad, 14-bit, 500 MSPS analog-to-digital converter (ADC). The device has an on-chip buffer and a sample-and-hold circuit designed for low power, small size, and ease of use. This device is designed for sampling wide bandwidth analog signals of up to 1.4 GHz. The AD9694 is optimized for wide input bandwidth, high sampling rate, excellent linearity, and low power in a small package.

hsc-jesd204High Speed Converter serial interface - JESD204

The JESD204 and the JESD204B revision data converter serial interface standard was created through the JEDEC committee to standardize and reduce the number of data inputs/outputs between high-speed data converters and other devices, such as FPGAs. Fewer interconnects simplifies layout and allows smaller form factor realization without impacting overall system performance.

Driven by demand for faster Internet connectivity, the Cable TV industry has developed new network architectures to deliver multi-gigabit services to subscribers. This “Fiber Deep” approach, using a “Remote PHY Device” (RPD), similar to a Remote Radio Head in wireless networks, moves critical hardware closer to the users using digital fibre. Whilst this saves space and reduces heat dissipation in the Converged Cable Access Platform (CCAP), it creates new design challenges.
