.Data Sheet.co.kr OKI Semiconductor ML87V2104 GENERAL DESCRIPTION PEDL87V2104DIGEST-01 Issue Date: Jan. 20, 2003 Preliminary Video Signal Noise Reduction and Field Rate Conversion IC with a Built-in 4M Bit Field Memory The ML87V2104 consists of a 3-port type (1 input port and 2 output ports) 4.4 Mbit (960 × 288 × 16bits) field memory and logic circuits for signal processing and memory control. The device can reduce field-recursive noise. Noise reduction auto mode can be set by detecting the noise in the vertical blanking period and by setting the noise reduction setting value according to the detected noise state. Moreover, an internal memory controller controls flicker-free conversion that doubles the vertical and horizontal direction frequencies.
