January 2008 P1708C rev 1.3 Low Power Notebook LCD Panel EMI Reduction IC 3 of 8 Notice: The information in this document is subject to change without notice. Spread Range Selection SR1 SR0 Spreading Range Modulation Rate 0 0 ± 1.00% (FIN/40) * 62.49 KHz 0 1 ± 2.00% (FIN/40) * 62.49 KHz 1 0 ± 0.25% (FIN/40) * 62.49 KHz 1 1 ± 0.75% (FIN/40) * 62.49 KHz Schematic for Notebook VGA Application Note: To set the P1708C to standby mode, disable the input clock (pin 1 CLKIN) and pull SSON (pin 5) low. Refer Standby Mode Selection Table. Absolute Maximum Ratings Symbol Parameter Rating Unit VDD, VIN Voltage on any pin with respect to Ground -0.5 to +7.0 V TSTG Storage temperature -65 to +125 °C TA Operating temperature 0 to +70 °C Ts Max. Soldering Temperature (10 sec) 260 °C TJ Junction Temperature 150 °C TDV Static Discharge Voltage (As per JEDEC STD22- A114-B) 2 KV Note: These are stress ratings only and are not implied for functional use. Exposure to absolute maximum ratings for prolonged periods of time may affect device reliability. Pin 8 can be tied either high or low, or it can be left unconnected. Tie SR0 and SR1 high/low according to spread range desired. External resistors are not needed to pull these pins high. Pin 5 SSON should be left unconnected to turn on spread spectrum. Pull this pin low to turn spread spectrum OFF and enable stand-by mode. 50MHz to 110MHz pixel clock input from VGA chip FB VDD 0.1µF 1 2 4 3 8 7 5 6 CLKIN VDD VSS ModOUT SSON SR1 SR0 NC P1708C 50MHz – 110MHz Pixel Clock Input from VGA Chip |
