DVB-C/T TV Receiver I2C-bus Full Band Tuner 

FEATURES

• Full frequency range from 51 to 860MHz for DVB-C /T
• Low IF tuner concept
• Programmable channel Filter bandwidth
• Active LT & single supply voltage
• Fully I2C bus controlled

 The half-NIM includes a full band tuner, an antenna loop through function (Active) and channel filtering for digital signals. It provides a low IF output after channel filtering to drive a DVB-C /T demodulator. Tuning, band switching and initialization are made via an I2C bus interface. The module is built on a low-loss printed circuit board carrying all the components in a metal housing frame with top and rear covers. The 2 aerial connectors are mounted on one frame side all other connections are made via pins at the bottom

7.Application Information

The module contains of one programmable part, the tuner IC TDA18250HN, which can directly be programmed by the I2C-bus 

7.1  Tuner

The source code for the TDA18250HN will be provided on request.

7.2  I2C Bus Requirements

The I2C implementation in the TDA18250HN follows the I2C bus specification, version 2.1, January 2000 as edited by Philips Semiconductors

7.3   I2C chip addresses

Write address: 0xC0, Read address: 0xC1

8.    Electrostatic Discharge

8.1   Test

Each device must be capable of normal performance following its subjection to the following tests:

 MIL STD 883C HBM

Test is performed with a voltage discharge from a 100 PF capacitor over a 1500 Ω series resistance in the discharge path. There is a direct contact between the test probe head and the unit under test, using the test points and conditions detailed below: 

• Test to pins 1 through last pin : 3 successive ESD discharges of  2 KVDC between each pin and the 

device frame. 

IEC 1000-4-2

Test is performed with a voltage discharge from a 150 PF capacitor over a 330 Ω series resistance in the discharge path. There is a direct contact between the test probe head and the unit under test, using the test points and conditions detailed below: 

•Test for antenna input socket  8 KVDC

•Test for antenna output socket  5 KVDC

8.2 Handling

Anyone handling a device must wear a properly grounded anti - static discharge bracelet to minimize ESD damage.

After each device is aligned and tested, it will be packed with anti - static poly-foam or material prior to transportation and storage. This protective foam is to remain in place until the device is assembled and soldered onto the receiver main board
