1. General description
The DAC1008D750 is a high-speed 10-bit dual channel Digital-to-Analog Converter
(DAC) with selectable 2

×
interpolating filters optimized for multi-carrier WCDMA
transmitters.
Because of its digital on-chip modulation, the DAC1008D750 allows the complex pattern
provided through lane 0, lane 1, lane 2 and lane 3, to be converted up from baseband to
IF. The mixing frequency is adjusted via a Serial Peripheral Interface (SPI) with a 32-bit
Numerically Controlled Oscillator (NCO) and the phase is controlled by a 16-bit register.
The DAC1008D750 also includes a 2

clock multiplier which provides the
appropriate internal clocks and an internal regulation to adjust the output full-scale
current.
The input data format is serial according to JESD204A specification. This new interface
has numerous advantages over the traditional parallel one: easy PCB layout, lower
radiated noise, lower pin count, self-synchronous link, skew compensation. The maximum
number of lanes of the DAC1008D750 is 4 and its maximum serial data rate is
3.125 Gbps.
The Multiple Device Synchronization (MDS) guarantees a maximum skew of one output
clock period between several DAC devices. MDS incorporates modes: Master/slave and
All slave mode.
