Innovator CU5-500BTD/BRD ATSC Transmitter/ Regenerative Translator System Description System Description The Innovator CXB Series Systems are of two different types. They are either Regenerative Translators or DTV Transmitters. The Regenerative Translator (BRD) accepts an RF On Channel signal (-79 to –8 dBm) and converts it to a DTV RF On Channel output signal. The DTV Transmitter (BTD) takes a SMPTE-310 Input and converts it to a DTV RF On Channel output signal.
Innovator CU5-500BTD/BRD ATSC Transmitter/ Regenerative Translator System Description In an (BRD) system, the 8 VSB signal on any VHF or UHF channel at J1, -8 to -79 dBm, connects to the tuner input of J1 on the 8 VSB demodulator board. The board demodulates the signal and supplies a SMPTE-310 output which connects to J42 on the 8 VSB modulator board. In an (BTD) system, the input SMPTE-310 at J1 connects directly to J42 on the 8 VSB modulator board.
Innovator CU5-500BTD/BRD ATSC Transmitter/ Regenerative Translator Web Ethernet Interface Description (Optional) Innovator CXB Series Web Ethernet Interface The (Optional) Innovator CXB Series Web Ethernet Interface (1310183) allows for the monitoring and control of the Innovator CXB Series system without the need for special software on the remote computer.

Innovator CU5-500BTD/BRD ATSC Transmitter/ Regenerative Translator Board Descriptions Circuit Descriptions of Boards in the CU5, CU30, CU50 & CU100 Transmitters (A1) 8 VSB Demodulator Board (1308275) - Only used with BRD operation Overview The 8 VSB demodulator assembly receives an off air 8 VSB signal on any VHF or UHF channel and demodulates this to an MPEG-2 transport stream that is per the SMPTE310M standard.
Innovator CU5-500BTD/BRD ATSC Transmitter/ Regenerative Translator Board Descriptions Channel Coder The FPGA subsequently uses the SMPTE-310 clock and data as the input to the channel coder contained inside the FPGA. The channel coder is a series of DSP blocks defined by the ATSC standard for 8 VSB data transmission. These blocks include the data randomizer, Reed Solomon Encoder, data interleaver, trellis coder, and sync inserter.
Innovator CU5-500BTD/BRD ATSC Transmitter/ Regenerative Translator Board Descriptions The +12V SYS also connects through the resistor R81 to provide +5V EXT to the rest of the board, and to the regulators U23 that provides +3.3V to the rest of the board and to U27 that provides +1.8V output. The +3.3V also connects to U24 that supplies +1.5V output. The +12V SYS connects to the regulator U25 and U26 to supply the +5VA output.
Innovator CU5-500BTD/BRD ATSC Transmitter/ Regenerative Translator Board Descriptions IF output level of the board. By controlling the value of the voltage applied to the pin diodes, the IF signal level is maintained at the set level. When the IF signal passes out of the pin-diode attenuator through C7, it is applied to the modular amplifier U1. This device contains the biasing and impedance-matching circuits that makes it operate as a wide-band IF amplifier.
Innovator CU5-500BTD/BRD ATSC Transmitter/ Regenerative Translator Board Descriptions The pre-distorted IF signal, in the Quadrature Phase path, connects to the op amp U11 whose output gain is set by R102, which provides a means of balancing the level of the Quad Phase pre-distorted IF signal that connects to Port 2 on the combiner Z4. The Quadrature and In Phase pre-distorted IF signals are combined by Z4, amplified by U10 and connected through C57 to the S Port of the splitter Z2.
Innovator CU5-500BTD/BRD ATSC Transmitter/ Regenerative Translator Board Descriptions If the ALC cannot increase the input level enough to satisfy the ALC loop, due to the lack of range, an ALC fault will occur. The fault is generated because U3C pin 9, increases above the trip point set by R47 and R50 until it conducts. This makes U3C pin 8, high and causes Q3 to conduct, which lights the Red ALC Fault LED DS1.

U8A, U8B and their associated components diode-or the metering voltages, which generates this cutback. The forward power is scaled to 2V = 100 % and the reflected power is scaled to 2V = 25%. The Reflected metering voltage is doubled again by U8B so that when the voltage of U8B exceeds the voltage at the output of U8A, the reflected power takes over the ALC circuit.
Innovator CU5-500BTD/BRD ATSC Transmitter/ Regenerative Translator Board Descriptions approximately 14 dB of gain. The board uses a power supply voltage of 24V. The RF transistors are operated at a voltage of 24V generated by the voltage regulators U6 and U7 for Q2, U5 and U3 for Q3 and U1 and U3 for Q1, which provide a separate regulated voltage to each transistor.
Innovator CU5-500BTD/BRD ATSC Transmitter/ Regenerative Translator Board Descriptions characteristic impedance of the input and output sides, matching networks are placed ahead and behind the amplifier blocks. Transformers Z3 and Z4 at the input to V1 and V2 and Z5 and Z6 at the output of V1 and V2 serve to balance the input and output signals. The paralleling circuit is achieved using the 3-dB input coupler Z1 and the second part of Z1, which is the 3-dB output coupler.
