Pin no. 1 2 Pin VSS1 XtalIN XtalOUT (MUTE) Crystal oscillator input switching (CHABLK) I2C clock input LC oscillator connections Crystal oscillator (MUTE input) Ground Function Ground connection (digital system ground) These pins are used either to connect the crystal and capacitors used to form an external crystal oscillator circuit to generate the internal synchronizing signals, or to input an external clock signal (2fsc or 4fsc). As a mask option, the XtalOUT pin can be set to function as the MUTE input pin. When this pin is set low, the video output is held at the pedestal level. (A pull-up resistor is built in and the input has hysteresis characteristics.) Switches the mode between external clock input and crystal oscillator operation. A low level selects crystal oscillator operation and a high level selects external clock input. As a mask option, the CTRL1 input pin can be set to function as the CHABLK (character . frame) output. This is a 3-value output. Clock input for the PDC/VPS data output. I2C bus. Connection for the external coil and capacitor for the oscillator used to generate the character output dot clock Outputs the state of the external synchronizing signal presence/absence judgment. Outputs a high level when synchronizing signals are present. Outputs either the crystal oscillator clock if CS and RST are low, or the VCO clock if CS and RST are high. (This signal is not output after a command reset.) Enable input for the OSD serial data input. Serial data input is enabled when this pin is low. A pull-up resistor is built in and the input has hysteresis characteristics. Serial data input enable pin. A pull-up resistor is built in and the input has hysteresis characteristics.

Once written, a first byte command identification code is stored until the next first byte is written. However, when the display character data write command (COMMAND1) is written, the LC74775/M locks into the display character data write mode, and another first byte cannot be written. When the CS pin is set high, the LC74775/M is set to the COMMAND0 (display memory write address setup mode) state.

The electrolytic capacitor connected to SYNIN must be connected with the correct polarity when a sync tip level of 1.4 VDC (CVIN input signal: sync tip = 1.4 V) is selected in the options for video signals generated with internal synchronization. When VDD1 is 5.0 V, the SYNIN input video signal pedestal level will be clamped to about 2.5 V.
Specifications of any and all SANYO products described or contained herein stipulate the performance, characteristics, and functions of the described products in the independent state, and are not guarantees of the performance, characteristics, and functions of the described products as mounted in the customer's products or equipment. To verify symptoms and states that cannot be evaluated in an independent device, the customer should always evaluate and test devices mounted in the customer's products or equipment. SANYO Electric Co., Ltd. strives to supply high-quality high-reliability products. However, any and all semiconductor products fail with some probability.
