Tr i path Technol ogy, I nc. - Technical Information TLD4012 ADSL LINE DRIVER USING TRIPATH DIGITAL POWER PROCESSING (DPP) TECHNOLOGY Technical Information Revision 2.0a – May 2002 GENERAL DESCRIPTION The TLD4012 is an ADSL line driver that provides very low power consumption and low distortion in a very small package as a result of Tripath’s proprietary power processing technology. This device accepts differential input signals from an analog front-end (AFE), and can be used in full-rate (G.dmt), or G.lite systems. This TLD4012 offers a low power consumption of 650mW for full-rate, full-power, CO-side, FDM (non-overlapped) transmissions. APPLICATIONS FEATURES Full-rate or G.lite line cards DSLAMs DLC equipment Central office switches BENEFITS Reduced line card power Reduced system power Increased line card density More ports per cubic foot of system space Improved system performance Simplifies thermal management on PCB Improved reliability Flexible solution Tripath Proprietary Power Processing technology Very low power consumption PCONS(Full-rate ADSL) = 650 mW (typ) PCONS (G.lite) = 390 mW (typ) Low distortion Spurious free dynamic range = -80 dBc 26kHz to 138kHz, RLINE=100, PLINE=19.8dBm Third harmonic distortion = -83 dBc at f = 100 kHz, -82 dBc at f = 500 kHz, -63 dBc at f = 1 MHz, VOUT = 10Vpp (differential), 70 load 500 mA minimum output current into a 71 load Digitally programmable gain (from 12.8 to 27.8 dB in 1 dB steps) Low-power mode -130 mW typical (line te……
