· Compliant to ANSI T1.413 I2
· Compliant to ETSI ETR 328
· Performance measurements according to ITU-T G.996.1 (G.test)
· OAM functionality according to ITU-T G.997.1 (G.ploam)
· Max. 16 Mbit/s downstream and 2 Mbit/s upstream data rate
· S=1/2 supported
· Fully echo cancelled for overlapped spectrum operation
· Double upstream mode for Annex B via firmware upgrade
· Trellis coding and Viterbi decoding
· Bit swapping upstream/downstream
· Very low noise (S/N>80dB) in downstream and upstream direction
· ATM UTOPIA-2 interface (50 MHz, 16 bit/8 bit)
· On chip ATM-TC layer
· Pseudo STM mode via UTOPIA
· 8-bit parallel host interface
· All memory on-chip, no external memory required for GEMINAX-D
· Built in PLLs and clock generation
· Configurable digital and analog test loops
· Future proof due to software upgrade options
· Dr.DSL(TM) firmware running on GEMINAX-D for ADSL pre-qualification, bundle management and maintenance
· Single-ended testing supported by Dr.DSL(TM) software
· Simplified PCB layout withP-TQFP packages (< 1.1 inch2 area per channel, including external parts, transformer and layout space),
· With P-LBGA packages < 0.9 inch2 area per channel (including external parts, transformer and layout space)
· < 1 W power dissipation per channel (20 dBm line level)
· Power down mode on per channel and block basis
· Support of power down wake up by CPE activity
· -40°C to +85°C operating range

PEB22720 Typical Application

· ADSL DSLAM systems
