Overview
The AD9125BCPZRL is a dual-channel, 16-bit TxDAC+ digital-to-analog converter with a maximum sampling rate of 1000 MSPS. It features flexible CMOS interfaces supporting dual-word, word, or byte loading modes. The device includes a high-performance PLL clock multiplier and digital inverse sinc filter. Full-scale output current is adjustable from 8.7 mA to 31.7 mA via an external resistor. Power consumption is specified at 900 mW under full operating conditions at 500 MSPS. The component is housed in a 72-lead LFCSP package.
Feature Summary
- Dual 16-bit DACs with 1000 MSPS sample rate
- Integrated 2x/4x/8x interpolator and complex modulator
- Adjustable analog output current (8.7 mA to 31.7 mA)
- High-performance low-noise PLL clock multiplier
Applications
- Wireless infrastructure transmitters
- Digital high or low IF synthesis
- W-CDMA, CDMA2000, TD-SCDMA, WiMAX, GSM, LTE systems
- Transmit diversity applications
Procurement Notes
Verify the BC suffix indicates the commercial temperature range (-40°C to +85°C) and the RL suffix denotes reel packaging. Confirm the specific lot date code and RoHS compliance status directly with the manufacturer or authorized distributor prior to ordering. Ensure the 72-lead LFCSP footprint matches the design layout.
Selection Notes
Select this component for direct conversion transmit architectures requiring high dynamic range. The integrated complex modulator simplifies baseband processing by allowing carrier placement anywhere within the DAC bandwidth. Verify that the host system supports the required CMOS interface speeds up to 250 MHz for the chosen interpolation mode.
Part Context
This part belongs to the Analog Devices TxDAC+ family, designed for high-speed data conversion. The AD9125 specifically targets multi-carrier generation up to the Nyquist frequency. It is optimized for seamless interfacing with analog quadrature modulators such as the ADL537x series.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation.
