rate (up to 4.0 Gbps versus the standard rate of 3.125 Gbps,
a 28% increase) and transmitter reach (up to 100 cm versus
the standard reach of 20 cm, a 400% increase). The enhanced
CGV features include Multi Device Synchronization (MDS),
which is not specified, but informatively discussed in the
JEDEC specification. NXP has implemented this optional
feature to enable LTE MIMO base station and other advanced
multichannel applications. NXP’s implementation of MDS
enables up to sixteen DACs data streams to be sample
synchronized and phase coherent.
This new interface has numerous advantages over the traditional
parallel one: easy PCB layout, lower pin count, reduced PCB
layers and cost, lower radiated noise, selfsynchronous link, skew
compensation.
Other features include a two’s complement or binary-offset data
format, and 74 dBc IMD3 at F_DAC = 640 Msps and F_OUT = 154 MHz.
DAC1408D series also include an LVDS compatible clock with
multiplier capable of x2, x4 and x8 operation and internal
regulation to adjust the output full scale current up to 20 mA.
A digital offset correction can be used to adjust the common
mode level at the DAC output. And 2 embedded auxiliary DACs
-current mode sources allow offset compensation between the
DAC and the next stage in your transmission path.
