Dual Channel Central Office ADSL2+ Line Features Driver
Drives 400m A at 16VP-P on ±12V supplies
The ISL1535 is a very low power dual channel differentiated
21.4VP-P differential output drive into 100Ω
amplifier designed for central office line driving for DMT
ADSL2+ solutions. This device features a high drive 20.6VP-P minimum differential output drive into 60Ω
capability of 600m A while consuming 5.2m A of supply
-75d Bc typical driver output distortion driving 50Ω at 1MHz
current per amplifier from ±12V supplies. This driver and 1/2-IS bias current achieves a typical distortion of less than -75d Bc, at 1MHz
Quiescent current of 5.2m A per amplifier in 1/2-IS mode
into a 50Ω load. The ISL1535 is available in 28 Ld HTSSOP package. This device is specified for operation over the full 100MHz BW at AV = 10 -40°C to +85°C temperature range.
Current control pins to select power modes
The ISL1535 has two control pins, C0 and C1, per channel.
Pin-to-pin replacement for EL1527 and EL1537
With the selection of C0 and C1, the device can be set into
Pb-free plus anneal available (Ro HS compliant)
full-IS power, 3/4-IS power, 1/2-IS power, and power-down disable modes. The ISL1535 maintains excellent distortion
Applications
and load driving capabilities even in the lowest power settings. The ISL1535 has extended bandwidth, low THD ADSL, ADSL2, ADSL2+ line drivers and high slew rate for ADSL2+ applications.
