General Description
Bt835 General Description
The Bt835 VideoStream III Decoder is a high quality single-chip, composite NTSC/PAL/SECAM video and S-Video decoder. Low operating power consumption and power-down capability make it an ideal low-cost solution for PC video capture applications on both desktop and portable system platforms. The Bt835 supports square pixel and CCIR601 resolutions for NTSC, PAL, and SECAM video. The Bt835 has a sophisticated 3-line adaptive comb filter to maintain full vertical video resolution and eliminate traditional comb filter artifacts. The Bt835's flexible pixel ports support digital video input as well as VIP and ByteStream interfaces to popular graphics controllers.

NOTE(S):
Stresses above those listed may cause permanent damage to the device. This is a stress rating only, and functional operation at these or any other conditions above those listed in the operational section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
This device employs high-impedance CMOS devices on all signal pins. It must be handled as an ESD-sensitive device. Voltage on any signal pin that exceeds the power supply voltage by more than +0.5 V, or drops below ground by more than 0.5 V, can induce destructive latchup.
