The MAX9568 is a stand-alone device, and requires no external components to set timing or bias voltage. The MAX9568 has high input impedance, eliminating the need for a low-impedance video source at the input. The MAX9568 provides composite sync, vertical sync, and horizontal sync outputs. The MAX9568 provides automatic SDTV, EDTV, and HDTV detection logic outputs to indicate the type of TV standard being processed. The MAX9568 provides a back-porch clamp output signal. The MAX9568 provides a loss-of-sync output to indicate a loss-of-video input signal. The MAX9568 provides an output to indicate odd and even fields. The MAX9568 provides a vertical interval coast output which allows control of a PLL oscillator when coasting through the vertical interval. Component Video Input (CVIDIN) CVIDIN provides a high input impedance to the analog video source. This eliminates the requirement for a lowimpedance video source. Following the input buffer is the sync slicer block. This block establishes a DC level for the incoming video signal. The sync information is stripped by using a comparator with threshold or slice level that automatically adjusts to the incoming signal. When the incoming signal has bilevel syncs, the slice is made 95mV above the sync tip. When the incoming signal has trilevel syncs, the slice is made 145mV above the sync tip. The device’s wide dynamic range, 0.2V to VCC - 0.2V, allows the video signal from 0.5VP-P to 2VP-P to be processed and operate in the linear range. The mentioned threshold levels are independent of the signal amplitude. CVIDIN is biased to 0.35 x VCC through a 300kΩ resistor. Use a 0.1µF capacitor to AC-couple at the input if the input signal is not within the input-voltage range, as shown Figure 3. INPUT-VOLTAGE RANGE MATRIX VCC - 0.2V 2.7V < VCC < 5.5V 0.5V (-6dB) 2V (+6dB) 1V (0dB) 2V (+6dB) 0.2V 0.5V (-6dB) Figure 3. Input-Voltage Range Matrix 12 ______________________________________________________________________________________ Component Analog TV Sync Separator Coast The MAX9568 provides a vertical interval coast output which allows the PLL oscillator to coast through the vertical interval. This output pulses low during vertical blanking interval. Vertical Sync Output (VSYNCOUT) VSYNCOUT produces a pulse signal that defines the beginning of a new field in interlaced systems or frame in progressive systems. This output pulses low whenever the vertical sync pulse interval is detected. See Figure 4 for vertical sync output timing diagrams. Horizontal Sync Output (HSYNCOUT) HSYNCOUT produces a pulse signal that defines the beginning of the horizontal line. This output pulses low whenever a horizontal sync pulse is detected. For interlace standards, the horizontal pulse output rate remains constant. See Figures 2a and 2b for horizontal sync output timing diagrams. Standard- and High-Definition TV Detection (SDTV, HDTV, HL) SDTV, HDTV, and HL produce logic outputs that indicate the standard of the component video signal at the input. SDTV output high indicates standard-definition television while SDTV output low indicates extended definition or high-definition television. HDTV output high indicates high-definition television while HDTV output low indicates standard-definition or extended definition television. HL output high indicates 625i, 625p (576p), and 1080i standards while HL output low indicates 525i, 525p (480p), and 720p standards. See Table 1. Odd and Even Field Detection (ODD/EVEN) ODD/EVEN produces a square wave that identifies the present field of an interlaced video source. ODD/EVEN output low indicates odd field while ODD/EVEN output high indicates even field. This square wave changes coincidentally with the beginning of the vertical pulse. Applications Information Chroma Filter If the input signal is standard-definition composite video, a simple lowpass filter is recommended in front of the input to attenuate the chroma signal, or any highfrequency noise below the black level. As shown in Figure 5, when the input is standard-definition video, SDTV is logic-high and Q1 is turned on. When Q1 is on, R1 and C2 form a 600kHz lowpass filter to attenuate high-frequency noise and improve the performance of the MAX9568. When the input is high-definition video or extended definition video, SDTV is logic-low and Q1 is turned off, disabling the RC input filter. BILEVEL SYNC PULSES CVIDIN VSYNCOUT tVP TRILEVEL SYNC PULSES CVIDIN VSYNCOUT Loss-of-Sync Output (LOS) LOS produces logic output that indicates the presence of a video input signal. LOS output high indicates that there is a sync or video signal at the input while LOS low indicates the presence of a component video signal at CVIDIN. tVP Figure 4. Vertical Sync Output Timing Diagrams R1 1kΩ Clamp Pulse Output (CLAMP) CLAMP produces a pulse signal that is generally used to drive a black-level clamp circuit which restores the DC component to a video signal. This output pulses low during black-level (back porch) of each video line. See Figures 2a and 2b for clamp pulse output timing diagrams.

This output contains all the information below the component video black level. CSYNCOUT is pulled high whenever sync is not detected at the component video input. See Figures 2a and 2b for composite sync output timing diagrams.
