ISL1550
ISL1550 is VDSL2 Differential Line Driver manufactured by Renesas.
features a high current drive capability of ±750m A 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 -66d Bc in VDSL2 8b upstream (US) 1 band and MBPR’s of -61d Bc and -60d Bc in VDSL2 17a US1 and US2 respectively.
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 15m A to 32m A, depending on its power setting. The...
