16-Bit, 5.9Gsps Wideband Interpolating and

Modulating RF DAC with JESD204B Interface

General Description

Beneﬁts and Features

The MAX5857 high-performance, interpolating and modulating,

16-bit, 5.9Gsps RF DAC can directly synthesize up to

1.2GHz of instantaneous bandwidth from DC to

frequencies greater than 2.6GHz. The device is optimized

for cable access and digital video broadcast applications

and meets spectral emission requirements for a broad set

of radio transmitters and modulators including DOCSIS

3.1/3.0, DVB-C2, DVB-T2, DVB-S2X, ISDB-T, and EPoC.

The device integrates interpolation filters, a digital quadra-

ture modulator, a numerically controlled oscillator (NCO),

clock multiplying PLL+VCO and a 14-bit RF DAC core. The

4x linear phase interpolation filter simplifies reconstruction

filtering, while enhancing passband dynamic performance

and reducing the input data bandwidth required from an

FPGA. The NCO allows for fully agile modulation of the

input baseband signal for direct RF synthesis. The complex

data path can be bypassed to access the RF DAC core

directly.

● Simplifies RF Design and Enables New

Communication Architectures

• Eliminates I/Q Imbalance and LO Feedthrough

• Enables Multi-Band RF Modulation

● Direct RF Synthesis of 1.2GHz Bandwidth

• 5.898Gsps DAC Output Update Rate

• High-Performance 14-Bit RF DAC Core

• Digital Baseband I/Q with 4x Interpolation

• Bypass Path Without Interpolation for Real RF

• Digital Quadrature Modulator+NCO for Full Agility

• Sub-1Hz NCO Resolution

• Integrated Clock Multiplying PLL+VCO

● Highly Flexible and Configurable

• 3, 4, 5, or 6-Lane JESD204B Input Data Interface

• Subclass-0 Compliant

• Up to 9.8304Gbps Per Lane

• Divided Reference Clock Output

• SPI Interface for Device Conﬁguration

The MAX5857 input interface accepts 16-bit input data

through a six-lane JESD204B SerDes data input interface

that is Subclass-0. The interface can be configured for 3,

4, 5, or 6 lanes and supports data rates up to 9.8304Gbps

to optimize the I/O lane count and speed.

The MAX5857 clock input has a flexible interface that

accepts a differential sine-wave or square-wave input

clock signal up to 5.9GHz. A bypassable clock multiplying

PLL and VCO can be used to internally generate the high-

frequency sampling clock using a reference frequency

between 245.76MHz and 1.475GHz. The device provides

a divided reference clock to ensure synchronization

between the data source and the DAC.

Applications

● DOCSIS 3.1 Remote PHY and CCAP

● Digital Video Broadcast Modulators

• DVB-C2/DVB-T2/DVB-S2X/ISDB-T

● Ethernet PON Over Coax (EPoC)

● Point-to-Point Wireless

● Instrumentation

The integrated RF DAC uses a differential current-

steering architecture that includes a differential 50Ω

internal termination and can produce a 3.2dBm full-scale

output signal level on a 50Ω external load. Operating

from 1.0V and 1.8V power supplies, the device consumes

2.7W at 4.9Gsps. The device is offered in a compact 144-

pin, 10mm x 10mm, FCCSP package and is specified

for the extended industrial temperature range (-40°C to

+85°C).
