Description
The MB86064 and MB86065 are part of the Fujitsu
second generation of high-performance digital to
analog converters (DACs).
Both devices feature the market’s shortest propagation
delay combined with superior time-domain response for
control-based applications that require low latency.
Robust data interfacing to compatible FPGAs and
ASICs is assured by a proprietary Loop-Clock
architecture. This unique solution automatically
maintains critical clock-to-data timing across variations
in process, voltage and temperature (PVT). No
calibration is required during production or lifetime
operation, reducing total system costs.

MB86064 Dual 14-bit 1.0GSa/s DAC
MB86065 Single 14-bit 1.3GSa/s DAC
The MB86064 is ideally suited to radio applications,
providing dual transmit or transmit with diversity. The
MB86065 supports conversion rates up of up to
1.3GSa/s, which enables higher generating frequencies
combined with wider spurious-free generating regions.
