PRODUCT HIGHLIGHTS

Diversity radio systems

1. An on-chip PLL allows users to provide a single ADC

sampling clock; the PLL multiplies the ADC sampling

clock to produce the corresponding JESD204A data rate

clock.

2. The configurable JESD204A output block supports up to

1.6 Gbps per channel data rate when using a dedicated

data link per ADC or 3.2 Gbps data rate when using a

single shared data link for both ADCs.

3. Proprietary differential input that maintains excellent SNR

performance for input frequencies up to 250 MHz.

4. Operation from a single 1.8 V power supply.

5. Standard serial port interface (SPI) that supports various

product features and functions, such as data formatting

(offset binary, twos complement, or gray coding),

controlling the clock DCS, power-down, test modes,

voltage reference mode, and serial output configuration.

Multimode digital receivers (3G and 4G)

GSM, EDGE, W-CDMA, LTE,

CDMA2000, WiMAX, TD-SCDMA

I/Q demodulation systems

Smart antenna systems

General-purpose software radios

Broadband data applications

Ultrasound equipment
