SGLS386F – JANUARY 2009 – REVISED OCTOBER 2014 DAC5670-SP 14-Bit 2.4-GSPS Digital-to-Analog Converter (DAC)
1 Features 3 Description The DAC5670 is a 14-bit 2.4-GSPS DAC with dual
demultiplexed differential input ports. The DAC5670
is clocked at the DAC sample rate and the two input
ports run at a maximum of 1.2 GSPS. An additional
reference bit input sequence is used to adjust the
output clock delay to the data source, optimizing the
internal data latching clock relative to this reference
bit with a delay lock loop (DLL). Alternatively, the DLL
may be bypassed and the timing interface managed
by controlling DATA setup and hold timing to
DLYCLK.
The DAC5670 can also accept data up to 1.2 GSPS
using only the A input port. In the single port modes,
options include: repeating the input sample (A_ONLY
mode), 2Г— interpolation by zero stuff (A_ONLY_ZS
mode), or 2Г— interpolation by repeating and inverting …
