Single Port, VDSL2 Differential Line Driver  
ISL1550  
The ISL1550 is a dual operational amplifier intended to be  
used as a differential line driver. ISL1550’s high bandwidth  
and low distortion performance enables the support of VDSL2  
8b, 17a and 30a modem applications.  
Features  
• 20dBm output power capability  
• Drives up to ±750mA from a +12V supply  
• 18V  
P-P  
differential output drive into 20Ω  
• -89dBc typical driver output distortion at full output at  
200kHz, 12V differential  
This device features a high current drive capability of ±750mA  
required to drive large voltage peaks into heavy loads. In  
Central Office (CO) applications, the driver achieves a typical  
Missing Band Power Ratio (MBPR) of -66dBc in VDSL2 8b  
upstream (US) 1 band and MBPR’s of -61dBc and -60dBc in  
VDSL2 17a US1 and US2 respectively.  
P-P  
• -61dBc US1, -60dBc US2 avg. MBPR 17a  
• Supply range: ±4.0V to ±6.6V, +8.0V to +13.2V  
• Thermal shutdown  
• K.20, GR-1089 Surge Robustness Validated  
The ISL1550 has two bias current control pins (C0, C1) to allow  
for four power settings (disable, low, medium, high). The VDSL  
modem DSP configures the line driver’s power setting based  
on the desired mode of operation. The line driver operates on a  
nominal single +12V or a dual ±6V supplies with bias current  
in active mode between 15mA to 32mA, depending on its  
power setting. The ISL1550’s gain setting is configurable at  
the application level by setting the Rf and Rg resistor values.  
The surge current handling of ISL1550 has been enhanced to  
allow ITU-T K.20 and GR1089 compliance with minimal  
external surge protection circuitry.  
Applications  
• VDSL2 Profiles: 8MHz, 17MHz, and 30MHz
