The ISL5857 is a 12-bit, 260+MSPS (Mega Samples Per Second), CMOS, high speed, low power, D/A (digital-to-analog) converter designed specifically for use in high performance communication systems such as base transceiver stations utilizing 2.5G or 3G cellular protocols. This device complements the ISL5x57 family of high speed converters, which include 10, 12, and 14-bit devices.
Key Features
- Low power: 103mW with 20mA output at 130MSPS
- Adjustable full scale output current: 2mA to 20mA
- +3.3V power supply
- 3V LVCMOS compatible inputs
- Excellent spurious free dynamic range (73dBc to Nyquist, fS = 130MSPS, fOUT = 10MHz)
- UMTS adjacent channel power = 70dB at 19.2MHz
- EDGE/GSM SFDR = 90dBc at 11MHz in 20MHz window
- Pin compatible, 3.3V, lower power replacement for the AD9752 and HI5860
- Pb-free (RoHS compliant)
Applications
- Cellular Infrastructure - single or multicarrier: IS-136, IS-95, GSM, EDGE, CDMA2000, WCDMA, TDS-CDMA
- BWA infrastructure
- Medical/test instrumentation
- Wireless communication systems
- High resolution imaging systems
