le9500 Zarlink Semiconductor, le9500 Datasheet - Page 4

• Manufacturer Part Number: le9500
• Description: Igh-voltage Ringing Slic Device For Volp Applications
• Manufacturer: Zarlink Semiconductor

The Le9500 device uses a voltage feed-current sense architecture. The transmit gain is a transimpedance. The Le9500 device
transimpedance is set via a single external resistor, and this device is designed for optimal performance with a transimpedance
set at 300 V/A. This interface is single ended. The Le9500 device offers a differential receive interface with a gain of 8.
The Le9500 device is internally referenced to 1.5 V. This reference voltage is output at the V
is also referenced to 1.5 V. The RCVP/RCVN receive inputs are floating inputs.
The Le9500 device is available in a 28-pin PLCC package.
