TA1317N

The TA1317N incorporates EW, vertical distortion correction circuit and dynamic focus correction circuit designed as a deflection processor IC for a large and wide picture tube which can control various functions via I2C BUS line.

The features of TA1317N can be summarized as (1)vertical drive (AC/DC-coupling); (2)picture height adjustment; (3)vertical shift adjustment; (4)vertical symmetry correction; (5)vertical linearity correction; (6)vertical S correction; (7)vertical integral correction; (8)vertical/Horizontal EHT compensation; (9)EW drive (parabola/PWM output); (10)picture width; (11)EW trapezium correction; (12)EW parabola correction; (13)EW corner correction (top only/bottom only/top&bottom); (14)EW S correction; (15)center curve correction (SAW/PAR); (16)parabola output for horizontal and vertical dynamic focus (h/v output independently); (17)horizontal and vertical dynamic focus phase adjustment; (18)horizontal and vertical dynamic focus amplitude adjustment; (19)horizontal dynamic focus curve characteristic adjustment; (20)V-ramp limiter circuit; (21)analog blanking output.

The absolute maximum ratings of TA1317N are (1)power supply voltage  VCCmaxl:  12 V; (2)input pin signal voltage  einmax:  9 Vp-p; (3)power dissipation  PD(Note 1: See the figure below):  1250  mW; (4)power dissipation reduction rate 1/ja:-10  mW/°C; (5)operating temperature  Topr: -20~65 °C; (6)storage temperature  Tstg: -55~150  °C(Note 2: Since the device is susceptible to surge, handle with care. Especially pin 32 has a low surge resistance. ).
