DS33Z11
Ethernet Mapper
www.maxim-ic.com
GENERAL DESCRIPTION
The DS33Z11 extends a 10/100 Ethernet LAN
segment by encapsulating MAC frames in HDLC or
X.86 (LAPS) for transmission over a PDH/TDM data
stream. The serial link supports bidirectional-
synchronous interconnect up to 52Mbps over xDSL,
T1/E1/J1, T3/E3, V.35/Optical, OC-1/EC-1, or
SONET/SDH Tributary.
The device performs store-and-forward of packets
with full wire-speed transport capability. The built-in
Committed Information Rate (CIR) controller
provides fractional bandwidth allocation up to the line
rate in increments of 512kbps. The DS33Z11 can
operate with an inexpensive external processor,
EEPROM or in a stand-alone hardware mode.
