TC90A46F General Description

The TC90A46F is a noise reduction IC for PAL which is used together with TC90A36F (field double-speed conversion), the device realizes a noise reduction (NR) function. As input data, the and signals processed by TC90A36F are used. The input and signals are digitally processed and their noise is reduced (YNR, CNR). As memory, general-purpose memory (4m bit EDO) is used.

The features of TC90A46F can be summarized as (1)realizes PAL noise reduction in combination with TC90A36F; (2)noise reduce processing between and frames using 4M bit memory.; (3)motion detector circuit built in.; (4)EDO memory controller built in.; (5)variable NR level; (6)Y/C digital interface; (7)interface with microcontroller using I2C bus; (8)5V single power supply.

The functions of TC90A46F can be summarized as (1)VDD: digital VDD (±5%); (2)CAS: CAS signal; (3)RST: system reset signal; (4)RAS: CAS signal; (5)NRWE: memory write enable; (6)OMSEL: test pin; (7)SCL: I2C bus clock input; (8)SDA: I2C bus data input/output; (9)VSS: digital VSS; (10)NFIIC: I2C bus noise filter switch; (11)W2CKI: double clock input; (12)TEST0: test pin; (13)WCKI: clock input; (14)TEST1: test pin; (15)HREF: horizontal reference input and so on.
