EL1537 ® Data Sheet December 14, 2005 Dual Channel Central Office ADSL2+ Line Driver The EL1537 is a very low power dual channel differentiated amplifier designed for central office line driving for DMT ADSL solutions. This device features a high drive capability of 400mA while consuming only 7.5mA of supply current per amplifier from ±12V supplies. This driver achieves a typical distortion of less than -75dBc, at 1MHz into a 50Ω load. The EL1537 is available in the thermally-enhanced 28-pin HTSSOP package. This device is specified for operation over the full -40°C to +85°C temperature range. Features • Drives 400mA at 16VP-P on ±12V supplies • 44VP-P differential output drive into 100Ω • 37.2VP-P minimum differential output drive into 60Ω • -75dBc typical driver output distortion driving 50Ω at 1MHz and 1/2-IS bias current • Low quiescent current of 3.9mA per amplifier in 1/2-IS mode • 50MHz BW at AV = 10 The EL1537 has two control pins, C0 and C1, per channel. With the selection of C0 and C1, the device can be set into full-IS power, 3/4-IS power, 1/2-IS power, and power-down disable modes. The EL1537 maintains excellent distortion and load driving capabilities even in the lowest power settings. The EL1537 has extended bandwidth and improved THD and slew rate for ADSL2+ and VDSL applications. • Power-down disable mode Ordering Information • G.SHDSL, HDSL2 line drivers PART NUMBER PART MARKING FN7433.2 • Pin-to-pin replacement for EL1527 • Pb-free plus anneal available (RoHS compliant) Applications • ADSL, ADSL2, ADSL2+ line drivers • VDSL line drivers PACKAGE TAPE & REEL PKG.
