The Advance Information presented herein represents a product that is developmental or prototype. The noted characteristics are design targets. Integrated Device Technologies, Inc. (IDT)

1. General description
The DAC1658Q and the DAC1653Q are high-speed high-performance 16-bit quad
channel digital-to-analog converter (DAC) with high and low common-mode output. The
devices provide a sample rate up to 1.50 Gsps with selectable
,  and  interpolation
filters optimized for multi-carrier and broadband wireless transmitters.
When both devices are referred to in this data sheet, the following convention will be
used: DAC165xQ.
The DAC165xQ integrates a JESD204B high-speed serial input data interface running up
to 10 Gbps allowing quad channel input sampling at up to 750 Msps over eight differential
lanes. It offers numerous advantages over traditional parallel digital interfaces:
Easier Printed-Circuit Board (PCB) layout
Lower radiated noise
Lower pin count
Self-synchronous link
Skew compensation
Deterministic latency
Multiple Device Synchronization (MDS); JESD204B subclass 1 support
Harmonic clocking support
Assured FPGA interoperability
There are two versions of the DAC165xQ:
Low common-mode output voltage (part identification DAC1653Q)
High common-mode output voltage (part identification DAC1658Q)
Two optional on-chip digital modulators convert the complex I/Q pattern from baseband to
IF. The mixer frequency is set by writing to the Serial Peripheral Interface (SPI) control
registers associated with the on-chip 40-bit Numerically Controlled Oscillator (NCO). This
accurately places the IF carrier in the frequency domain. The 13-bit phase adjustment
feature, the 12-bit digital gain and the 16-bit digital offset enable full control of the analog
output signals.
The DAC165xQ is fully compatible with device subclass 1 of the JEDEC JESD204B
standard, guaranteeing deterministic and repeatable interface latency using the
differential SYSREF signal. The device also supports harmonic clocking to reduce
system-level clock synthesis and distribution challenges.
