EL1529IL-T7集成電路（IC）的驅動器接收器收發(fā)器規(guī)格書PDF中文資料

The EL1529 is to be used with Globespans G7566-850 CO chipset for high performance long reach and high speed applications, including ADSL2, ADSL2+, G.Span, and G.Span+.

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 overall 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 can be set using a resistor on the IADJ pin. Two other pins (C0 & C1) can also be used to adjust supply current to one of four pre-set modes (full-IS, 3/4-IS, 1/2-IS, 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 -40°C to +85°C temperature range.
