CS8952

CrystalLAN™ 100BASE-X and 10BASE-T Transceiver

Features

! Six LED drivers (LNK, COL, FDX, TX, RX,

and SPD)

! Single-Chip IEEE 802.3 Physical Interface IC

for 100BASE-TX, 100BASE-FX and

10BASE-T

! Low power (135 mA Typ) CMOS design

operates on a single 5 V supply

Description

! Adaptive Equalizer provides Extended

Length Operation (>160 m) with Superior

Noise Immunity and NEXT Margin

! Extremely Low Transmit Jitter (<400 ps)

! Low Common Mode Noise on TX Driver for

Reduced EMI Problems

! Integrated RX and TX Filters for 10BASE-T

! Compensation for Back-to-Back “Killer

Packets”

The CS8952 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 cir-

cuitry has been designed to provide extremely low

transmit jitter (<400 ps) for improved link partner perfor-

mance. Transmit driver common mode noise has been

minimized to reduce EMI for simplified FCC certification.

! Digital Interfaces Supported

The CS8952 incorporates a standard Media Indepen-

dent Interface (MII) for easy connection to a variety of 10

and 100 Mb/s Media Access Controllers (MACs). The

CS8952 also includes a pseudo-ECL interface for use

with 100Base-FX fiber interconnect modules.

– Media Independent Interface (MII) for

100BASE-X and 10BASE-T

– Repeater 5-bit code-group interface

(100BASE-X)

– 10BASE-T Serial Interface
