SKKD162-18E Datasheet The Chroma filters are one half the bandwidth of the Luminance filter therefore the propagation delay time through the Chroma filter is longer than the Luminance filter. In the Standard Definition (SD) case, the Chroma filter propagation delay is typically 60 nanoseconds longer than the Luminance filter. This is three clock cycles at 54MHz so it is easily corrected by adding digital delay as shown in Figure 3 and illustrated as a shift register in Figure 2. In the High Definition (HD) setting the Chroma filter propaga- tion delay is typically 15 nanoseconds longer than the Luminance filter. This is one clock cycle at 74.25MHz so it is also easily corrected by adding digital delay to the luminance path. SKKD162-18E Price
SKKD162-18E on stock Low Supply Operation The LTC3413 is designed to operate down to an SVIN input supply voltage of 2.25V. One important consideration at low input supply voltages is that the RDS(ON) of the P- channel and N-channel power switches increases. The user should calculate the power dissipation when the LTC3413 is used at 100% duty cycle with low input voltages to ensure that thermal limits are not exceeded. This input is used for two functions. When not used it should be connected to VDD via a 10kl resistor. The first function utilizes the input signal as the frequency source for the timekeeping counters. This function is selected by setting bit 6 in the Clock Control Register. The second function enables the line input to sense a power failure. Threshold detectors operating above and below VDD sense an AC voltage loss. Bit 5 must be set to "1" in the Interrupt Control Register and crystal or external clock source operation is required. Bit 6 in the Clock Control Register must be low to select XTAL operation. |
