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 feature a JESD204B compatible high-speed serial input data interface running up to 10 Gbps.

· The DAC165xD series includes two versions: DAC1653D with low common-mode output voltage and DAC1658D with high common-mode output voltage.

FEATURES

· Easier PCB layout, lower radiated noise, and lower pin count compared to traditional parallel interfaces.

· Self-synchronous link with skew compensation and deterministic latency.

· Supports Multiple Device Synchronization (MDS) and harmonic clocking.

· Includes an optional on-chip digital modulator with a 40-bit Numerically Controlled Oscillator (NCO).

· Features 13-bit phase adjustment, 12-bit digital gain, and 16-bit digital offset for full control of analog output signals.

· Available in a VFQFP-N 56 package (8 mm × 8 mm).

APPLICATIONS

· Ideal for LTE and LTE-A MIMO transceiver applications.

· Suitable for multi-carrier and broadband wireless transmitters.

· Effective in systems requiring deterministic and repeatable interface latency.

· Useful in scenarios demanding harmonic clocking to reduce system-level clock synthesis and distribution challenges.
