CS4954-CQZ

The CS4954-CQZ belongs to the CS4954 series. It is a NTSC/PAL digital encoder. It provides full conversion from digital video formats YCbCr or YUV to NTSC and PAL composite,Y/C (S-video) and RGB,or YUV analog video. It is available in 48-TQFP package which is lead free.

There are CS4954-CQZ features as follows. (1) six DACs providing simultaneous composite,S-video, and RGB or Component YUV outputs; (2) programmable DAC output currents for low impedance (37.5 ) and high impedance(150 ) loads; (3) multi-standard support for NTSC-M, NTSCJAPAN,PAL; (4) ITU R.BT656 input mode supporting EAV/SAV codes ; (5) programmable HSYNC and VSYNC timing; (6) multistandard teletext support; (7) VBI encoding support; (8) Wide-Screen Signaling (WSS) support; (9) NTSC closed caption encoder with interrupt; (10) CS4955 supports Macrovision copy protection version 7; (11) host interface configurable for parallel or I2CR compatibleoperation; (12) on-chip voltage reference generator.

The following is about CS4954-CQZ absolute maximum ratings. (1): power supply is from -0.3 V to 6.0 V; (2): input current per pin is from-10 mA to 10 mA; (3): output current per pin is from -50 mA to 50 mA; (4): analog input voltage is from -0.3 V to VAA+0.3 V; (5): digital input voltage ranges from -0.3 V to VDD+0.3 V; (6): ambient temperature power applied is from -55 to 125 ; (7): storage temperature is from -65 to 150; (8): high level input voltage is from 2.2 V to VDD+0.3 V; (9): input leakage current is from -10 A to 10 A; (10): the maximum allowable junction temperature is 150 .
