Operating Ratings indicate conditions for which the device is functional but do not guarantee specific performance limits. For guaranteed specifications and test conditions, See the Electrical Characteristics. The guaranteed specifications apply only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under the listed test conditions. 3. VCC supply pins 6, 9, and 23 must be externally wired together to prevent internal damage during VCC power on/off cycles. 4. The supply current specified is the quiescent current for VCC1/VCC2 and VCC3 with RL = ∞ . The supply current for VCC3 (pin 23) also depends on the output load. 5. Output voltage is dependent on load resistor. Test circuit uses RL = 390Ω 6. Measure gain difference between any two amplifiers Vin = 560mVpp. 7. When measuring video amplifier bandwidth or pulse rise and fall times, a double sided full ground plane printed circuit board without socket is recommended. Video amplifier 10MHz isolation test also requires this printed circuit board. The reason for a double sided full ground plane PCB is that large measurement variations occur in single sided PCBs. 8. Adjust input frequency from 10MHz (AV max reference level) to the-3dB frequency (f -3dB). 9. Measure output levels of the other two undriven amplifiers relative to the driven amplifier to determine channel separation. Terminate the undriven amplifier inputs to simulate generator loading. Repeat test at fin = 10MHz for Iso_10MHz. 10. A minimum pulse width of 200 ns is guaranteed for a horizontal line of 15kHz. This limit is guaranteed by design. if a lower line rate is used a longer clamp pulse may be required. 11. During the AC test the 4V DC level is the center voltage of the AC output signal. For example. if the output is 4Vpp the signal will swing between 2V DC and 6V DC. 12. These parameters are not tested on each product which is controlled by an internal qualification procedure. 1. 2. 14 I2C BUS CONTROLLED R/G/B VIDEO AMPLIFIER FOR MONITORS S1D2500A01 FUNCTIONAL DESCRIPTION Contrast (OSD Contrast Adjustment) (8-bits) The contrast adjustment is made by controlling simultaneously the gain of three internal variable gain amplifiers through the I2C bus interface. The contrast adjustment allows you to cover a typical range of 38dB. Brightness Adjustment (8-bits) The brightness adjustment controls to add the same black level (pedestal) to the 3-channel/R/G/B signals after contrast amplifier by I2C BUS. Cut-Off Brightness Adjustments (8-bits) The Cut-Off Brightness adjustment is made by simultaneously controlling the external cut-off current. Cut-Off (SUB Contrast) Adjustment (8-bits × 3) These adjustments are used to adjust the white balance, and the gain of each channel is controlled by I2C BUS. The SUB contrast adjustment allows you to cover a typical range of 11dB. OSD Inputs The S1D2500A01 includes all the circuitry necessary to mix OSD signals into the R/G/B video signal. You need 4 pins for this function. (R/G/B OSD, OSD blanking) Serial Interface The 2-wires serial interface is an I2C BUS interface. The slave address of the S1D2500A01 is DC (hexadecimal) Bit8 1 Bit7 1 Bit6 0 Bit5 1 Bit4 1 Bit3 1 Bit2 0 Bit1 0 (W) Data Transfer All bytes are sent MSB (Most Significant Bit) bit first and the write data transfer is closed by a stop. The MCU can write data into the S1D2500A01 registers. To do that, after a start, the MCU must send: - The I2C address slave byte with a low level for R/W bit (bit1) - The byte of the interinal register address where the MCU wants to write data (SUB Address) - The data - Stop 15 S1D2500A01 I 2C BUS CONTROLLED R/G/B VIDEO AMPLIFIER FOR MONITORS I2C BUS Write Operation MSB LSB SCL transter SDA START Slave address ACK Register address ACK Data byte
