Dual 16-bit, 1.6-GSPS DAC synthesizes high-quality wideband signals from baseband to high intermediate frequencies
1/4/2013 10:00 AM EST
Analog Devices, Inc. has introduced the AD9142 dual-channel,
16-bit, 1.6-GSPS D/A converter, which supports high data rates and
complex modulation schemes required in communications, test and
instrumentation, and defense and aerospace systems.
The combination of programmable interpolation rate, high
sample rates, and fine NCO modulation capability gives system designers
flexibility when choosing D/A converter output frequencies. This is
especially helpful in meeting four- to six-carrier GSM transmission
specifications and other communications standards. Operating with the
on-chip PLL (phase-locked loop) at a D/A converter output frequency of
200 MHz, the AD9142 delivers a 79-dB ACLR (adjacent-channel leakage
ratio) for six-carrier GSM applications.
The AD9142 includes integrated interpolation filters with selectable
interpolation factors of 2, 4, and 8. The dual D/A converter data
interface supports word and byte load allowing customers to reduce input
pins on lower data rates to save board space, power and cost. The
AD9142 is available in a space-saving 72-pin LFCSP (lead-frame
Availability and Pricing
The AD9142 packaged in a 72-lead 10x10mm LFCSP is available now and is priced at $41.40 each In 1,000 quantities.
