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 TDMA PHY Burst Receiver and the
BCM3037 Universal Burst Modulator chips from Broadcom.
The BCM93138 has several 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 transmitter is the BCM3037 Universal QPSK/16-QAM
Burst Modulator capable of operating in all
DOCSIS/EuroDOCSIS modes with integrated 10-bit DAC and
pre-equalization. The transmitter can operate in both continuous
and burst modes. The BCM3034 Universal headend modulator is
used to emulate advanced TDMA PHY equipped CPE by
creating the upstream advanced TDMA PHY signal for system
evaluation.
The FPGA controller has a 64K x 16-bit RAM for pattern storage
and/or data capture. It also implements basic
DOCSIS/EuroDOCSIS MAC functions, data generation and
verification. Access to the controller is via a printer port or RS-
232 to PC host.
The BCM93138 represents the industry’s first complete
DOCSIS/EuroDOCSIS-based silicon solution for the cable
upstream channel supporting advanced TDMA PHY features and
is based on Broadcom’s field-proven QAMLink^® technology. It
comes complete with schematics, gerber file, Bill of Materials
(BOM), data sheet, software source code and application support.
