National Semiconductor introduced the wire with at least LVDS chipset

October 26, 2005 - China News - National Semiconductor Corporation (National Semiconductor Corporation) (NYSE symbol: NSM) today introduced a new high-speed low-voltage differential signaling ( LVDS) serializer / deserializer chipset, the advantage is to use a differential twisted pair cable (ie, two wires) with the 24-bit data serial, and TC58A040F datasheet and then transferred to flat panel displays. 800 x 480 resolution with degree of liquid crystal displays, for example, this model for the DS90C241 and TC58A040F price and DS90C124 serial / deserializer chipset only uses two wires, compared to the previous generation of LVDS interface products you need to use 8 wires, but no difference between the image clarity. Since this serial / deserializer chip set data path can be reduced, thereby reducing printed circuit board layers and TC58A040F suppliers and pin number, but also ensure that the system can use smaller cables and connectors, in other words, by chipset saves system cost.

This DS90C241/124 chipset for a variety of different devices, including car navigation system and rear seat infotainment systems, cabin entertainment systems, surveillance systems, remote display system, CMOS / CCD imaging system point of sale terminals and automatic teller machines. The chipset features AC coupling support, DC balance and pre-emphasis, it can support up to 10 meters of cable.

National Semiconductor Flat Panel Display Products Product Director Todd D. Whitaker said: "The automotive semiconductor market is currently growing at double-digit, the growth rate of particular interest. As most of the luxury cars are installation of navigation, safety and infotainment systems, liquid crystal display devices has become one of the standard car. National Semiconductor developed specifically for automobile manufacturers that a DS90C241/DS90C124 chipset, to ensure that cars can use less interconnect and the longer cables in order to reduce the overall system cost. "

DS90C241 and DS90C124 chipset About

DS90C241/DS90C124 chipset can be sent using an embedded clock LVDS differential pairs twisted wire cable to convert the 24 bits of data. In addition to the chipset interconnect needed can be reduced, there are many other advantages, such as for LVDS differential twisted pair cables to provide AC coupling support, the pre-enhancement signal can be strengthened to ensure the transmitted signal cable can be further extended. In addition, the chipset uses proprietary data encoding technology, supported by the serial line DC balanced bit stream transmission. Other important features and benefits include:

a.. Operating frequency of between 5 and 35 MHz, and is available to support a variety of different degree of liquid crystal display resolution

B.. 24:1 serial data payload (payload) and 840 Mbps bandwidth,

C.. Applies to -40 ° C to 105 ° C wide temperature range

D.. AC coupled to provide support for serial line short-circuit protection

E.. DC balance transfer

F.. 3.0V to 3.6V voltage range

G.. Deserializer reference clock or oscillator without external support

H.. Programmable pre-emphasis to ensure the system can drive a longer cable signal

I.. Less electromagnetic interference



Price and Availability National Semiconductor is now available for individual customers and DS90C124 DS90C241 chip samples, and is scheduled to March 2006 started to provide quantities. Both chips are 48-pin TQFP package (7mm x 7mm x 1mm), procurement of the same 1,000-unit quantities is $ 6 price of the same.
