These DACs feature wide output bandwidth and adjustable output current up to 60mA, making them ideal for generating high frequency or broadband signals. The double data rate (DDR) LVDS interface requires 16 lanes for up to 1.25Gsps data rate or 32 lanes for operation up to 2.5Gsps. Features • Exceptional Spectral Purity – 80dBc SFDR at 70MHz fOUT –68dBc SFDR at 1000MHz fOUT • High Full-Scale Output Current (up to 60mA) • Wide Analog Output Bandwidth (2.1GHz) • Low Latency (7.5/11 cycles) • 625MHz DDR LVDS or DHSTL Interface – 2.5Gsps Using 32 Lanes – 1.25Gsps Using 16 Lanes • 9mm x 15mm 170-Pin BGA Package Additive Phase Noise –100 Info & Free Samples www.linear.com/product/LTC2000 fOUT = 65MHz fDAC = 2.5Gsps –110 Phase Noise (dBc/Hz) 1-800-4-LINEAR –120 –130 –140 –150 –160 –170 –180 0.01 video.linear.com/5091 0.1 1 10 Offset Frequency (kHz) 100 1000 , LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks of Linear Technology Corporation.
