STV7622 192 output plasma display panel data driver
The STV7622 is a data driver for Plasma Display Panels (PDP) designed in the ST’s proprietary BCD high-voltage technology.
It controls up to 192 outputs via an input data bus (3, 6 or 2 x 3-bits wide) operating at up to 60MHz. This large number of outputs reduces the number of connections between the controller board and the data driver ICs.
The STV7622 contains a new logic input stage that minimizes EMI resulting from the transmission of high speed TTL or LVCMOS data and clock signals. This new input stage is RSDS compliant. It enables increasing the operating frequency without compromising noise immunity.
The input data bus is configured by dedicated input pins:
- BS1 and BS2: bus width select (3, 6, 2 x 3 bits or RSDS mode)
- DIR input: shift register loading direction
The STV7622 output stage integrates several ST patented functions aimed at reducing EMI without compromising addressing speed or performance of the PDP modules.
These functions mainly consist of:
- SmartSlope: controls the output falling edge speed /shape
- ConstantSlope: controls the output rising edge speed
- Spread Spectrum Jitter (SSJ): controls the spread of the output rising edge
The STV7622 is powered by a separate 70V supply for the high-voltage outputs and a 5V supply for the logic. All command input levels are 5V CMOS as well as 3.3V compatible
