CH7307C-DEF

The CH7307C-DEF is designed as one kind of display controller device that includes a low jitter PLL for generation of the high frequency serialize clock, and all circuitry required to encode, serialize and transmit data. This device accepts data over one 12-bit wide variable voltage data port which supports four different RGB data formats.

Features of the CH7307C-DEF are:(1)DVI Transmitter up to 165MHz; (2)DVI low jitter PLL; (3)DVI hot plug detection; (4)Provides 10-bit high speed video DAC for RGB output; (5)DAC connection detect; (6)Programmable power management; (7)Fully programmable through I2C port; (8)Complete Windows and DOS driver support; (9)Low voltage interface support to graphics device; (10)Offered in a 64-pin LQFP package.

The absolute maximum ratings of the CH7307C-DEF can be summarized as:(1)DVDD, AVDD, TVDD, VDD relative to GND: -0.5 to 5.0 V;(2)Input voltage of all digital pins: GND - 0.5 to VDD + 0.5 V;(3)Analog output short circuit duration: Indefinite Sec;(4)Ambient operating temperature: -55 to 85 °C;(5)Storage temperature: -65 to 150 °C;(6)Junction temperature: 150 °C;(7)Vapor phase soldering (one minute): 220 °C.

The electrical characteristics of CH7307C-DEF can be summarized as:(1)Video D/A resolution: 10 Bits;(2)Full scale output current: 33.89 mA;(3)Video level error: 10 %;(4)VDD & AVDD current: 90 mA;(5)DVDD, TVDD (3.3V) current: TBD mA;(6)DVDD2 (1.8V) current (15pF load): 4 mA.
