It is used for CI module supply, when Module is inserted (it means CI detect is low) This
circuit is opened or closed by CI_POWER_CTRL port of main uController
7. USB INTERFACE
Main Concept IC has integrated 2 USB 2.0 interface. One of them is used for ethernet
function, the other one is used for USB connectivity for last user. Last user can play video,
picture and audio files. Also digital channels can be record to externall storage device by
this interface. All SW files can be updated with interface.
USB circuit has 3 main parts
Integrated USB 2.0 Host interface of D3K (U5)

8. DDR2 SDRAM K4T1G164QF (U155)
Description:
The 1Gb DDR2 SDRAM is organized as a 16Mbit x 8 I/Os x 8 banks, 8Mbit x 16 I/Os x 8
The 1Gb DDR2 SDRAM is organized as a 16Mbit x 8 I/Os x 8 banks, 8Mbit x 16 I/Os x 8
banks device. This synchronous device achieves high speed double-data-rate transfer
rates of up to 1066Mb/sec/pin (DDR2-1066) for general applications. The chip is designed
to comply with the following key DDR2 SDRAM fea-tures such as posted CAS with
additive latency, write latency = read latency - 1, Off-Chip Driver(OCD) impedance
adjustment and On Die Termination. All of the control and address inputs are
synchronized with a pair of exter-nally supplied differential clocks. Inputs are latched at
the crosspoint of dif-ferential clocks (CK rising and CK falling). All I/Os are synchronized
with a pair of bidirectional strobes (DQS and DQS) in a source synchronous fash-ion. The
address bus is used to convey row, column, and bank address information in a RAS/CAS
multiplexing style. For example, 1Gb(x8) device receive 14/10/3 addressing. The 1Gb
DDR2 device operates with a single 1.8V ± 0.1V power supply and 1.8V ± 0.1V VDDQ.
The 1Gb DDR2 device is available in 60ball FBGA(x8) and 84ball FBGA(x16).
Features:
• JEDEC standard VDD = 1.8V ± 0.1V Power Supply
• VDDQ = 1.8V ± 0.1V
• 533MHz fCK for 1066Mb/sec/pin
• 8 Banks
• Posted CAS
• Programmable CAS Latency: 4, 5, 6, 7
• Programmable Additive Latency: 3, 4, 5. 6
• Write Latency(WL) = Read Latency(RL) -1
• Burst Length: 4 , 8(Interleave/nibble sequential)
• Programmable Sequential / Interleave Burst Mode
• Bi-directional Differential Data-Strobe (Single-ended data-strobe is an optional feature)
• Off-Chip Driver(OCD) Impedance Adjustment
• On Die Termination
• Special Function Support - PASR(Partial Array Self Refresh) - 50ohm ODT - High
Temperature Self-Refresh rate enable
• Average Refresh Period 7.8us at lower than TCASE 85°C, 3.9us at 85°C < TCASE < 95
°C
• All of products are Lead-free, Halogen-free, and RoHS compliant
