CS8952T-IQ中文资料凌云逻辑数据手册PDF规格书

DESCRIPTION

The CS8952T uses CMOS technology to deliver a high-performance, low-cost 100BASE-X/10BASE-T Physical Layer (PHY) line interface. It makes use of an adaptive equalizer optimized for noise and near end crosstalk (NEXT) immunity to extend receiver operation to cable lengths exceeding 160 m. In addition, the transmit circuitry has been designed to provide extremely low transmit jitter (
