1. General description
2. Features and benefits
The DAC1208D750 is a high-speed 12-bit dual channel Digital-to-Analog Converter
(DAC) with selectable 2×, 4× or 8× interpolating filters optimized for multi-carrier WCDMA
transmitters.
Because of its digital on-chip modulation, the DAC1208D750 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 DAC1208D750 also includes a 2×, 4× or 8× 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 DAC1208D750 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.

... The DAC1208D750 must be configured before operating. Therefore, it features an SPI slave interface to access internal registers. Some of these registers also provide information about the JESD204A interface status. The DAC1208D750 requires both supplies of 3.3 V and 1.8 V. The 1.8 V supply has separate digital and analog power supply pins. The clock input is LVDS compliant. 10.2 JESD204A receiver The descrambler can be enabled/disabled Fig 3 ...

... As stated in JESD204A, the transmitter and the receiver first have to synchronize. This is achieved through SYNC_OUT signals and a sync pattern (K28.5 symbol). The receiver (i.e. DAC1208D750) first drives its SYNC_OUT outputs. The sync pattern is continuously sent until the receiver deasserts the SYNC_OUT signal. DAC1208D750 ...
