PRODUCT HIGHLIGHTS

APPLICATIONS

1. Integrated dual, 14-bit, 170 MSPS/250 MSPS ADC.

2. The configurable JESD204B output block supports up to

5 Gbps per lane.

3. An on-chip, phase-locked loop (PLL) allows users to provide a

single ADC sampling clock; the PLL multiplies the ADC

sampling clock to produce the corresponding JESD204B

data rate clock.

4. Support for an optional RF clock input to ease system board

design.

Diversity radio systems

Multimode digital receivers (3G)

TD-SCDMA, WiMAX, WCDMA, CDMA2000, GSM, EDGE, LTE

DOCSIS 3.0 CMTS upstream receive paths

HFC digital reverse path receivers

I/Q demodulation systems

Smart antenna systems

Electronic test and measurement equipment

Radar receivers

5. Proprietary differential input maintains excellent SNR

performance for input frequencies of up to 400 MHz.

6. Operation from a single 1.8 V power supply.

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

product features and functions such as controlling the clock

DCS, power-down, test modes, voltage reference mode, over

range fast detection, and serial output configuration.

COMSEC radio architectures

IED detection/jamming systems

General-purpose software radios

Broadband data applications
