popular 1117 voltage regulator. The TLV1117LV is an extremely low-power device that consumes 500 times
lower quiescent current than traditional 1117 voltage regulators, making it suitable for applications that
mandate very low standby current. The TLV1117LV family of LDOs is also stable with 0 mA of load current;
there is no minimum load requirement, making it an ideal choice for applications where the regulator is
required to power very small loads during standby in addition to large currents on the order of 1 A during
normal operation. The TLV1117LV offers excellent line and load transient performance, resulting in very small
magnitude undershoots and overshoots of output voltage when the load current requirement changes from less

Novatek NT72567 Block Diagram
10. 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 external storage device by this interface. All SW files can be updated with interface.
USB circuit has 3 main parts
o Integrated USB 2.0 Host interface of NT72567 (U112)
o Protection IC (U109) (optional*)
o Over Current Protection IC (U110) (optional*)
* The max current that can be supplied for USB loads does not cause a danger for main IC. So, these ICs are
used as optional.

11. DDR3 SDRAM K4B1G1646G 1GB G-DIE (U113)
The 1 GB DDR3 SDRAM G-die is organized as a 8Mbit x 16 I/Os x 8banks device. This synchronous
device achieves high speed double-data-rate transfer rates of up to 2133Mb/sec/pin (DDR3-2133) for general
applications. The chip is designed to comply with the following key DDR3 SDRAM features such as posted
CAS, Programmable CWL, Internal (Self) Calibration, On Die Termination using ODT pin and Asynchronous
Reset . All of the control and address inputs are synchronized with a pair of externally supplied differential
clocks. Inputs are latched at the cross point of differential clocks (CK rising and CK falling). All I/Os are
synchronized with a pair of bidirectional strobes (DQS and DQS) in a source synchronous fashion. The address
bus is used to convey row, column, and bank address information in a RAS/CAS multiplexing style. The DDR3
device operates with a single 1.5V ± 0.075V power supply and 1.5V ± 0.075V VDDQ. The 1 GB DDR3 G-die
device is available in 96ball FBGA(x16).
Features
• JEDEC standard 1.5V ± 0.075V Power Supply
