IDT Introduces Industry’s First Low-power Quad 16-bit DAC with JESD204B for Multi-carrier Broadband Wireless Applications

Business Wire
Integrated Device Technology, Inc. (IDT®) (NASDAQ: IDTI), the
Analog and Digital Company™ delivering essential mixed-signal
semiconductor solutions, today announced the industry’s first
low-power quad 16-bit digital-to-analog converter (DAC) featuring
the JESD204B high-speed serial interface. IDT’s new quad DAC
enables wide bandwidth support and eases board routing requirements
in multi-carrier broadband wireless applications.
The DAC165xQ is a quad 16-bit 1.5 Gsps DAC with 750 Msps input
data rate, enabling wide bandwidth support for use across various
base station transceiver (BTS) platforms. The integrated 10 Gbps
JESD204B interface improves system performance and greatly
simplifies routing and PCB stack-up by replacing 32 matched
differential lane pairs (common with traditional interfaces) with
up to eight high-speed differential lanes. The DAC165xQ supports
all popular wireless standards including MC-GSM with a wide
spurious-free dynamic range (SFDR = 85 dBc typ) and low noise
spectral density (NSD = -162 dBm/Hz typ) for improved signal
quality.
“Our new quad 16-bit DAC is a demand-driven extension of our
acclaimed dual 16-bit DAC announced last year,” said Christian
Kermarrec, vice president and general manager of Wireless Systems
at IDT. “Building upon our leading portfolio of wireless
communication solutions, the DAC165xQ complements our RF, data
compression, RapidIO®, and timing solutions to provide a
comprehensive system-solution. IDT is the only company to offer
this level of performance, integration, and features – empowering
BTS manufacturers to make large strides in system innovation.”
IDT’s JESD204B-enabled DAC integrates two complex numerically
controlled oscillators (NCOs) for intermediate frequency (IF)
mixing, a low noise bypass-able integrated phase-locked loop (PLL),
and various RF Mute modes to maximize flexibility and optimize
system cost. In addition, it features harmonic clocking and
deterministic latency to support beam-forming via
multi-device-synchronization (MDS). This enables multiple DAC
output streams to be sample-level synchronized and phase-coherent
for coordination at the system level. Additional applications
include communication systems based on LTE, LTE-A, LTE-TDD, W-CDMA,
LMDS/MMDS, point-to-point microwave backhaul, high-definition video
broadcast production equipment, automated test equipment (ATE), and
direct digital synthesis (DDS) instruments.
Product Availability
The IDT DAC1658Q and DAC1653Q are currently sampling to
qualified customers and are available in a 10
mm x 10 mm 72-pin HLA package. The DAC1658Q is a
high-output common mode voltage version (2.8 to 3.0 V), and
the DAC1653Q is a low-output common mode voltage version (0.25 to
0.5 V) for easy pairing with a wide range of IQ modulators.
Pin compatible dual-output devices are also available from IDT. For
