ADV7604BBCZ-5 is a digitizer that contains an HDMI receiver. A video digitizer is a module that takes an analog frame and converts it to a digital frame. The alternative term used for digitizer is a decoder. An analog image is decoded into a digital image. The key parameter to evaluate the performance of the digitizer is an SNR. SNR, referred to as the signal-to-noise ratio, of the module is high.

The module ADV7604BBCZ-5 is an efficient digitizer with a high-definition multimedia interface receiver.  In addition to the HDMI receiver module, one main component processor (CP) can process the video signal from the HDMI receiver. The YPrPB and RGB component formats can be programmed by using this CP feature. The receiver is 1:4 multiplexed and supports 36-/30-/24-bit deep color. The operating frequency of the HDMI receiver is 225 Mhz. The module ADV7604BBCZ-5 can be operated in dual mode, Mode 1 is HDMI quad, and mode 2 is analog input mode. This feature enables the module ADV7604BBCZ-5 to perform the simultaneous processing of the videos. Hence enhancing the switching between HDMI and ADC. The module offers a flexible audio interface and enables high-resolution audio. The receiver supports the audio up to eight channels. It also provides the utility of super audio CD (SACD) to represent the audio Signal by the oversampled 1-bit.

How is the module ADV7604BBCZ-5 decoding the input signal?  The first step of digitization is performed by the front-end ADC. 12 bit decoding is enabled by the front-end analog to digital converters. 12 channel Voltage clamp control loops can remove the dc off-sets from the video signals. Input mux allows multiple video signals simultaneously without the requirement of any external mux. Fine clamping is performed in the component processor unit. HDMI receive of ADV7604BBCZ-5 performs the active equalization of the data signals. Equalization is performed to tackle the channel effects and obtain highly efficient results. HDMI performs the equalization and reception of audio and video packets. The CP section contains the AGC block that can manually set the video gain automatically. Automatic adjustments include the contrast and brightness of the video signal.  

For video decoders, graphics function matters a lot. The module ADV7604BBCZ-5 provides versatile graphics functions.

Automatic contrast and brightness control, manual clamp and gain maintenance, 170 MSPS conversion rate to support high-resolution RGB input. And color space conversion feature. Instability of time biasing and an Enhanced standard definition processor performs synchronization; ESDP is available for different input modes and can identify the characteristic of the input. Depending on the characteristic, ESDP performs the automatic configuration for other information.

Samsung Electronics builds sixth domestic contract chip-making line – Latest News

Samsung Electronics Co Ltd has begun work on a sixth domestic contract chip production line, the company said, to make logic chips for mobile phones and computers as it looks to cut reliance on the volatile memory chip sector.

The South Korean firm is taking on bigger rival Taiwan Semiconductor Manufacturing Co Ltd (TSMC) in the contract manufacturing business, where it competes for orders from…

“According to a new report from Asia today, an ‘Apple tsunami’ is impacting on Samsung’s logic chip division, cornering top management to implement contingency plans to find new clients as Apple moves to other sources,” Jack Purcher reports for Patently…

APOLLO181 HOMEMADE 4-BIT TTL CPU performing an 8-bit multiplication (by ggunderscoreit)

So just in case you haven't been "in the know" about all of the contests electronics companies/organizations like to set up, here's another one from Dangerous Prototypes called the 7400 Contest.  Entries are due Oct 21st I believe.

First off, you can find all information about it here.  And secondly, the contest is essentially for you to use 7400 logic.  And demonstrate what 7400 logic was/wasn't meant to do.  This of course requires that you know what 7400 logic is, and I don't!

So 7400 logic chips are known as TTL or transistor-transistor logic chips.  TTL chips are made of resistors and BJTs.  And they are known as logic chips because they create logic gates and those logic gates can be employed in higher level uses such as shift registers, amplifiers, etc.

There are many, many different variations and these are all differentiated by their names.

Low-power TTL (L), which traded switching speed (33ns) for a reduction in power consumption (1 mW) 

High-speed TTL (H), with faster switching than standard TTL (6ns) but significantly higher power dissipation (22 mW)

Schottky TTL (S), used Schottky diode clamps at gate inputs to prevent charge storage and improve switching time. These gates operated more quickly (3ns) but had higher power dissipation (19 mW)

Low-power Schottky TTL (LS) – used the higher resistance values of low-power TTL and the Schottky diodes to provide a good combination of speed (9.5ns) and reduced power consumption (2 mW).  Probably the most common type of TTL, these were used as glue logic in microcomputers, essentially replacing the former H, L, and S sub-families.

Fast (F) and Advanced-Schottky (AS) variants of LS from Fairchild and TI, respectively, circa 1985, with "Miller-killer" circuits to speed up the low-to-high transition. These families achieved PDPs of 10 pJ and 4 pJ, respectively, the lowest of all the TTL families.

And just to show how different these can be:

These are labelled '00, 'LS7400, 'S00 and you can see just how different the circuits are, but that they are all made from transistors and resistors.
