Brief
BCM93138 ADVANCED PHY TRANSMITTER/RECEIVER EVALUATION SYSTEM
BCM93138 FEATURES
• The BCM93138 is a dual-channel upstream cable burst
transmitter/receiver evaluation system
• Support for advanced TDMA PHY layer functions for
DOCSIS/EuroDOCSIS, IEEE802.14, DAVIC and DVB
applications
• Programmable modulation formats including BPSK,
and QPSK up to 256 QAM
• ^{Frequency-agile from 5 to 65 MHz}
• ^{Flexible options for evaluating upstream analog front}
end (AFE)
• ^{Wideband external A/D with direct sampling}
• ^{Narrowband external A/D sampling}
• ^{Narrowband internal A/D sampling}
• ^{50 dB dynamic range for transmitter and receiver}
• ^{Full Reed-Solomon encoder/decoder with}
programmable 23-bit randomizer/derandomizer
• Multiple operation modes:
• ^Continuous
• ^{DOCSIS/EuroDOCSIS TDMA}
• ^{Random-arrival}
• ^{Easy-to-use Broadband Studio evaluation software}
SUMMARY OF BENEFITS
• The BCM93138 enables complete cable upstream
advanced PHY layer testing and evaluation with:
• ^{BCM3138: DOCSIS/EuroDOCSIS-based advanced TDMA}
PHY burst receiver
• ^{BCM3037: DOCSIS/EuroDOCSIS-based QPSK/16 QAM}
burst transmitter
• ^{BCM3034: DOCSIS/EuroDOCSIS-based advanced QAM}
modulator
• Dramatically reduces time to market by providing a
complete reference design for a DOCSIS/EuroDOCSIS
based advanced TDMA PHY cable upstream
implementation.
• Implements pre-equalization for improved
performance in heavily impaired cable channels.
• Enables digital cable set-top boxes, modems and
telephony implementations.
• Provides self-contained subscriber and headend system
with seamless interface between subscriber and
headend components.
• Windows software for running test functions and
scripts enable user-based evaluation tools with fast
turn-up.
• Windows software API for register, memory and
control access allows visibility to system performance
for design comparisons and tradeoffs.
