3 / 15 page DEVICES INCORPORATED Video Imaging Products 3 LF3338 8-Bit Vertical Digital Image Filter 04/06/1999–LDS.3338-B SIGNAL DEFINITIONS Power VCC and GND +3.3 V power supply. All pins must be connected. Clock CLK — Master Clock The rising edge of CLK strobes all enabled registers. Inputs DIN7-0 — Data Input DIN7-0 is the 8-bit registered data input port. Data is latched on the rising edge of CLK. VB7-0 — Field Filtering Data Input VB7-0 is the 8-bit registered data input port used only when implementing Odd and Even Field Filtering (see Functional Description section for a full discussion). Data is latched on the rising edge of CLK. CF11-0 — Coefficient Input CF11-0 is used to load data into the coefficient banks and configuration/ control registers. Data present on CF11-0 is latched into the LF InterfaceTM on the rising edge of CLK when LD is LOW (see the LF InterfaceTM section for a full discussion). CA7-0 — Coefficient Address CA7-0 determines which row of data in the coefficient banks is fed to the multipliers. CA7-0 is latched into the Coefficient Address Register on the rising edge of CLK when CEN is LOW. Outputs DOUT15-0 — Data Output DOUT15-0 is the 16-bit registered data output port. COUT7-0 — Cascade Data Output COUT7-0 is a 8-bit cascade output port. COUT7-0 on one device should be connected to DIN7-0 of another LF3338. Controls LD — Coefficient Load When LD is LOW, data on CF11-0 is latched into the LF InterfaceTM on the rising edge of CLK. When LD is HIGH, data can not be latched into the LF InterfaceTM. When enabling the LF InterfaceTM for data input, a HIGH to LOW transition of LD is required in order for the input circuitry to function properly. Therefore, LD must be set HIGH immediately after power up to ensure proper operation of the input circuitry (see the LF InterfaceTM section for a full discussion). PAUSE — LF InterfaceTM Pause When PAUSE is HIGH, the LF InterfaceTM loading sequence is halted until PAUSE is returned to a LOW state. This effectively allows the user to load coefficients and control registers at a slower rate than the master clock (see the LF InterfaceTM section for a full discussion). CEN — Coefficient Address Enable When CEN is LOW, data on CA7-0 is latched into the Coefficient Address Register on the rising edge of CLK. When CEN is HIGH, data on CA7-0 is not latched and the register’s contents will not be changed. FIGURE 2.
