DESCRIPTION

· DAC1653D and DAC1658D are high-speed, high-performance 16-bit dual channel Digital-to-Analog Converters (DACs).
· They support sample rates up to 2 Gsps with selectable ×2, ×4, and ×8 interpolation filters.
· These devices are optimized for multi-carrier and broadband wireless transmitters.
· They integrate a JESD204B compatible high-speed serial input data interface running up to 10 Gbps.
· The devices support dual channel input sampling at up to 1 Gsps over four differential lanes.

FEATURES

· Easier PCB layout with lower radiated noise and pin count.
· Self-synchronous link with skew compensation and deterministic latency.
· Multiple Device Synchronization (MDS) and harmonic clocking support.
· Assured FPGA interoperability.
· On-chip digital modulator for converting complex I/Q pattern from baseband to IF.
· 40-bit Numerically Controlled Oscillator (NCO) for accurate IF carrier placement.
· 13-bit phase adjustment, 12-bit digital gain, and 16-bit digital offset for full control of analog output signals.
· Internal regulator adjusts full-scale output current between 10 mA and 30 mA.

APPLICATIONS

· Multi-carrier and broadband wireless transmitters.
· LTE and LTE-A MIMO transceiver applications.
· Systems requiring high-speed, high-performance DACs with JESD204B interface.
