1 ? fn7406.1 el1529 dual channel differential dsl line driver for globespan co chipsets the el1529 is to be used wit h globespan's g7566-850 co chipset for high performance long reach and high speed applications, including ads l2, adsl2+, g.span, and g. spa n + . the el1529 is an integral part of the signal chain. the driver has been optimized for flat gain response and reduced harmonic distortion and noise in the bands of interest to improve the overa ll signal to noise in the system. these drivers achieve a total harmonic distortion (thd) measurement of typically -70db @ 1.1mhz, while consuming typically 5ma per dsl channel of total supply current. this supply current ca n be set using a resistor on the i adj pin. two other pins (c 0 & c 1 ) can also be used to adjust supply current to one of four pre-set modes (full-i s , 3/4-i s , 1/2-i s , and full power-down). the el1529 operates on 5v to 12v supplies and retains its bandwidth and linearity over the complete supply range. the device is supplied in the small footprint (4x5mm) 24-pin qfn package and is specified for operation over the full -40c to +85c temperature range. features ? 450ma output drive capability ?44.1v p-p differential output drive into 100 ? -85dbc thd @ 1mhz 2v p-p ? high slew rate of 500v/s ? bandwidth - 46mhz ? current control pins ? channel separation - 80db @ 500khz -75db @ 1mhz ? pb-free available (rohs compliant) applications ? adsl line drivers for globespan g7566-850 co chipsets pinout el1529 (24-pin qfn) top view vina+ vinb+ gnd iadj nc vinc+ vind+ vina- vinb- voutb voutc vinc- vind- voutd c1ab c0ab vs- nc vouta c1cd c0cd vs+ nc nc 19 18 17 16 15 14 13 24 23 22 21 20 8 9 10 11 12 1 2 3 4 5 6 7 thermal pad ordering information part number package tape & reel pkg. dwg. # el1529il 24-pin qfn - mdp0046 el1529il-t7 24-pin qfn 7? mdp0046 el1529il-t13 24-pin qfn 13? mdp0046 el1529ilz (see note) 24-pin qfn (pb-free) - mdp0046 EL1529ILZ-T7 (see note) 24-pin qfn (pb-free) 7? mdp0046 el1529ilz-t13 (see note) 24-pin qfn (pb-free) 13? mdp0046 note: intersil pb-free products employ special pb-free material sets; molding compounds/die attach materials and 100% matte tin plate termination finish, which are rohs compliant and compatible with both snpb and pb-free soldering operations. intersil pb-free products are msl classified at pb-free peak reflow temperatures that meet or exceed the pb-free requirements of ipc/jedec j std-020. data sheet february 11, 2005 caution: these devices are sensitive to electrosta tic discharge; follow proper ic handling procedures. 1-888-intersil or 1-888-352-6832 | intersil (and design) is a registered trademark of intersil americas inc. copyright intersil americas inc. 2004, 2005. all rights reserved all other trademarks mentioned are the property of their respective owners. get full datasheet
