BCM93138 - Advanced PHY Transmitter/Receiver Evaluation System

Advanced PHY Transmitter/Receiver Evaluation System

The BCM93138 is a complete cable network transceiver system for frequency-agile, time-division multiple access (TDMA) systems. It is an ideal platform for evaluating the BCM3138 Dual Universal Advanced PHY Burst Receiver and the BCM3037 Universal Burst Modulator chips from Broadcom. The BCM93138 has numerous modes of operation including random burst arrival, continuous mode and TDMA with various burst types like those defined in the DOCSIS/EuroDOCSIS standard. Burst data can be generated internally, programmed into internal memory, or supplied via an external test connector. A comprehensive software package is included to control and monitor the performance of the transceiver.
The receiver module operates in a 5-65 MHz range with multiple options for the analog front end. These include wideband direct sampling and narrowband sampling (typically using a low-IF carrier) with either external or chip-internal A/D converters. The receiver can operate in multiple modes: continuous mode, single burst type with external Receive_now, single burst type with random arrival and full DOCSIS/EuroDOCSIS burst types.

  • The BCM93138 is a dual-channel upstream cable burst transmitter/receiver evaluation system
  • Support for advanced PHY layer functions for DOCSIS/EuroDOCSIS, IEEE802.14, DAVIC and DVB applications
  • Programmable modulation formats including BPSK, and QPSK up to 64 QAM
