7. Device Descriptions
TU1000 - BTD-DU606Z
The Front End DTT (digital terrestrial) NIM module receives an off air UHF signal, and converts the digital
content into a parallel transport stream, to be fed into the MPEG decoder IC. This device is I2C controlled.
IC600 -TOP244Y
The TOP244Y is the Main PSU, PWM control IC. Supplied with a rectified AC source, this device produces
a Programmed PWM signal to control the Switch Mode PSU.
IC800 - CXA7002R-T6
The CXA7002R-T6 is an Audio/Video switch. It provides Audio and Video routing from the Digital decoder
source to the TV and VCR SCART connectors CN800 / 801. This device is I2C controlled.
IC700 - XWM8729ED/R
The XWM8729ED/R is a high performance DAC. It supports data input word lengths from 16 to 24 bits and
sampling rates up to 192 KHz. This device is I2C controlled.
IC200 - FS6128-04
This is a monolithic CMOS clock generator, with circuitry that implements a VCXO when an external
resonator is attached. 13.5MHz Xtal is attached - X200.
IC201 - UPD61120F1-100-JN1
The Multimedia microprocessor has the following functions, running main software application, MPEG
transport stream decoding + analogue video output ( internal video DENC ), Master I2C control, digital
audio output ( external Audio DAC required ).
IC300 / IC304 - TC58V64BFTEL, Y
These IC’s are single mount options. Both IC’s are Flash Memory IC’s, IC300 is a 128Mbit part ( 16M x 8
bits ) and IC304 is a 64Mbit part.
IC302 - MT46V8M16TG-75
This device is a high speed CMOS, dynamic random-access memory containing 134,217,728 bits. It is
internally configured as a quad-bank DRAM.
IC604 - PQ015EZ01ZP
This is a fixed 1.5V regulator, its main function is to supply the PWB with a 1.5V supply.
