Dual 16-bit, 1.6-GSPS DAC synthesizes high-quality wideband signals from baseband to high intermediate frequencies
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 chip-scale package).
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.
