STV6408

The STV6408 is designed as one kind of computer-controlled teletext device that supports facilities for reception and display of current level protocol data, and it belongs to the STV5348 family. Features of the STV6408 are:(1)complete teletext and vps decoder including an 8 page memory on a single chip; (2)upward software compatible with previous sgs-thomson's multichip solutions (saa5231, sda5243, stv5345); (3)perform pdc system a (vps) and pdc system b (8/30/2) data storage separatly; (4)dedicated "error free" output for; (5)valid pdc data indication of line 23 for external use; (6)single +5v supply voltage .single 13.875mhz crystal reduced set of external components, no external adjustment; (7)optimized number of digital signals reducing emc radiation; (8)high density cmos technology; (9)digital data slicer and display clock phase lock loop; (10)28 pin dip & so package.

The absolute maximum ratings of the STV6408 can be summarized as:(1)Positive Supply Voltage on VDDD and VDDA: -0.3 to 6.0 V;(2)Input Voltage (any input): -0.3 to VDD+0.5 V;(3)Output Voltage (any output): -0.3 to VDD+0.5 V;(4)Difference between VDDD, VDDA: 0.25 V;(5)Operating Ambient Temperature: 0 to +70 ;(6)Storage Temperature: -40 to +150 .

The electrical characteristics of this STV6408 can be summarized as:(1)Source Current (VCBLK = 2V, VCVBS = 0V): 80 uA;(2)Video Input Amplitude (peak to peak): 1 V;(3)Input Capacitance: 10 pF;(4)Delay from CVBS to TCS Output from STTV Pin: 200 ns;(5)Clamping Level at Synchro Pulse: 0 mV;(6)High Level Clamp Current (CVBS = VCLAMP + 1V): 5 uA;(7)Load Capacitance: 400 pF.
