7 / 11 page GENNUM CORPORATION 522 - 47 - 00 7 DETAILED DESCRIPTION 1. DATA INPUT AND OUTPUTS Data enters and exits the device on the rising edge of PCLK_IN as shown in Figures 1 and 2. This data can be scrambled or unscrambled and framed or unframed. 2. DESCRAMBLER AND FRAMER Both the descrambler and framer can be enabled or disabled independently of each other to allow the input to remain scrambled or unscrambled. If the data is unscrambled, it can be word aligned (framed) or passed through unaltered. 3. STANDARDS INDICATION VD_STD[3:0] indicates the standard that the device has detected. The states of VD_STD[3:0] are shown in the following standards indication tables. Note the following in the above tables: SMPTE260M is 1125 lines/frame SMPTE274M is 1125 lines/frame SMPTE295M is 1250 lines/frame SMPTE296M is 750 lines/frame See Table 1 for more specific details on the source format parameters. 67 EAV_ERR Synchronous wrt PCLK_IN Output Status signal output. Indicates a TRS error or a mismatch between the embedded TRS and the flywheel TRS when the flywheel is enabled. This signal is set high when an error in the EAV TRS is detected or when the internal flywheel indicates there is a mismatching EAV TRS. Refer to Fig. 3 for timing information of EAV_ERR relative to LUMA (DATA_OUT[19:10]) and CHROMA (DATA_OUT [9:0]). 70 TEST TEST Test pin. Used for test purposes only. This pin must be connected to GND for normal operation. 92, 96, 97, 98, 99,100,101 VDD N/A N/A Must be connected to VDD for normal operation. 95, 102 GND N/A N/A Must be connected to GND for normal operation. 103,104,105, 106, 107, 108, 111, 112, 113, 114, 117, 118, 119,120, 121, 122, 123, 124, 125, 126 DATA_IN [19:0] Synchronous wrt PCLK_IN Input Input data bus. DATA_IN [19] is the MSB of the signal (pin 103). DATA_IN [0] is the LSB of the signal (pin 126). This data is typically scrambled and not word aligned.
