BU RF Solutions 2. Pinning Configurations Both CU and TU have common pinning configurations. Refer to Table 2.1. SYMBOL DESCRIPTION RF Mod_in RF Modulator input (depends on versions) Ant_5V Antenna 5V [Do not connect if active antenna is not used.] Not connected 5V (LT) Loop Through Supply Voltage +5V (depends on version)
BU RF Solutions 3. Quick Startup Guide for the user. A quick guide is as followed. Further information and instructions for hardware and software requirements are given in the next sections. 1) Apply +5V power supply at connector 1000. 2) Connect parallel port from IIC controller (PC), which generates the IIC protocol connector 1040 (IIC Input Connector).
BU RF Solutions 4. An Overview of the Evaluation Board The evaluation board can be classified to few different sections. Refer to Diagram 4.1 /4.2. A. +5.0Volts power supply, 3.3Volts and 1.8Volts supplies via stabilizers for digital part. B. On-board IIC Interface. C.
BU RF Solutions 4.1. Board Settings. 4.1.1 Board Power Supplies +5.0 Volts A single 5Volts supply is needed via connector 1000. The 5 Volts is further regulated to different voltages required by the CU1216 and TU1216 products. +3.3V supply via stabilizer 7000. +1.8V / 2.5V supply via stabilizer 7001.
BU RF Solutions 5. Channel Decoder Software Guide and Installation This section provides some instructions for the channel decoder software installation and a quick guide to use it. CU1216 family uses the TDA10021 channel decoder intended for the reception of DVB_C compliant MPEG2 signals, transmitted via cable networks.

IF frequency Enter the IF center frequency delivered by the tuner (36.125 or 43.75Mhz). Enable reading Enable/disable to read the tuner PLL status.
BU RF Solutions 5.2.2 TDA10021 – A Quick Guide to Software Usage After the tuner is powered up for proper initialisation, the program can be launched. (Hint : Tuner OK indicator should be on to indicate 5V supply and IIC communication have been detected) Test procedure for CU1216 family : 1) Input the followings in the Main User Interface menu (refer to Figure 5.1) : Wanted RF frequency...

BU RF Solutions The Tuner register tab allows direct access to the Tuner’s registers. Here, settings for any IIC controlled tuner is allowed. The Demodulator register tab allows direct access to the TDA10046 registers. Simply double click on any of the registers to edit its value.
C communications are correct. In the control software window (press the configuration button), check the type of tuner used (should be set to PHILIPS). Is the tuner in lock? (First, allow the software to read the tuner registers). Is the gain in an automatic configuration? Is the RF input level correct?
