General description The DAC1403D160 is optimized to reduce architecture complexity and overall system cost. It leads to dynamic performance in multi-carrier support, because of its direct IF conversion capabilities. With an internal sampling rate of up to 160 MHz, DAC1403D160 is an extremely competitive solution for broadband wireless systems transmitters, as well as a wide range of applications. 2. Features I Dual 14-bit resolution I Spurious-Free Dynamic Range (SFDR) = 80 dBc at 2.5 MHz I Input data rate up to 80 MHz I 2 × interpolation ﬁlter I Output data rate up to 160 MHz I Single 3.3 V power supply I Low noise capacitor-free integrated Phase-Locked Loup (PLL) I Low power dissipation I HTQFP80 package I Ambient temperature from −40 °C to +85 °C 3. Applications I Broadband wireless systems I Digital radio links I Cellular base stations I Instrumentation I Cable modem I Cable Modem Termination System (CMTS)/Data Over Cable Service Interface Speciﬁcation (DOCSIS) 1 page NXP Semiconductors DAC1403D160 www.DataSheet4U.com Dual 14 bits DAC, up to 160 MHz, 2 x interpolating Table 2.
