1. General description
2. Features
The DAC1408D650 is a high-speed 14-bit dual channel Digital-to-Analog Converter (DAC)
with selectable 2 or 4 interpolating filters optimized for multi-carriers WCDMA
transmitters.
Thanks to its digital on-chip modulation, the DAC1408D650 allows the complex I and Q
inputs 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 DAC1408D650 also includes a 2 and 4 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.
DAC1408D650 maximum number of lanes is 4 and its maximum serial data rate is
3.25 Gbps.

Each DAC consists of a segmented architecture, comprising a 6-bit thermometer sub-DAC and an 8-bit binary weighted sub-DAC.

... Fig 3. JESD204A receiver The JEDEC204A defines the following parameters: The DAC1408D650 supports both LMF = 421 and LMF = 211. The current setting is configurable via the SPI registers interface. The complete Digital Layer Processing adds a variable delay on each lane path. This is mainly due to the inter-lane alignment. ...

Page 16

... As stated in JESD204A, transmitter and receiver have to first synchronize. This is achieved through SYNC_OUT signals and SYNC pattern (K28.5 symbol). The receiver (i.e. DAC1408D650) first drives its SYNC outputs. The SYNC signal/pattern is continuously sent until the receiver deasserts the SYNC signal. The Lane Processing makes use of the SYNC-patterns to synchronize the datastream, determine the initial running disparity and to extract the 10 bits word from the incoming datastream (word-alignment) ...

Page 17

... NXP Semiconductors The SYNC signal is also used during normal operation by the DAC1408D650 to request a link re-initialization. This occurs when the 8b/10b module loses synchronization. The SYNC_OUT signal conforms to LVDS signaling. Its common mode voltage (see 39 “Page 2 register allocation 39 “Page 2 register allocation SYNC_OUT is synchronous with the frame clock. ...
