It then converts the RGB signal from analog -to- digital by synchronizing to the generated clock. It has a maximum conversion speed of 180MHz and is capable of supporting up to UXGA (1600 × 1200).

Pre-amp Block Diagram 12 VOUT (to ADC) TRIPLE 8-BIT ANALOG-TO-DIGITAL CONVERTER KB2516 (Preliminary) Figure 1 is a block diagram of the pre-amp that is used in AD2516X. A clamp circuit is required to set the input DC level because the RGB signal input is AC coupled as it passes through the capacitor to be sent to the preamp. The signal to control the clamp is made from the HSYNC signal in the sync processor block. The clamp level control, which uses an 8-bit DAC, has two modes, first, the coarse level control that controls 3 RGB channels simultaneously and, second, the fine level control that controls each channel clamp level independently. The input signal is gain controlled through the 8-bit DAC for a maximum gain amplification of 2.3dB. As in the clamp level control, the pre-amp has two modes: 1.) coarse level control that controls 3 RGB channels simultaneously and 2.) fine level control which controls them independently.

ADC Block Diagram Figure 2 which has the 2-step pipeline configuration is a block diagram of the ADC used in AD2516X. It uses 1 overlap bit for digital correction and supports 3 output modes, signal channel mode, dual channel interleaving mode, and dual channel parallel mode. The sync processor block converts the HSYNC or SOG input to a positive HSYNC signal, which can be processed by PLL, and also makes the clock signal needed for clamp level control from the HSYNC. When HSYNC and SOG inputs enter simultaneously, it is designed to place priority on the HSYNC. 13 KB2516 (Preliminary) TRIPLE 8-BIT ANALOG-TO-DIGITAL CONVERTER CLKADC HSYNCH DIVCK HSYNCH PFD DIVCK VCO Phase Shifter MUX 0/180 MUX 0/180 CKB MUX 0/180 CKC Divider SYNCHRO 12 bits from Micom HSYNCO, VSYNCO Figure 3. PLL Block Diagram Figure 3 is a block diagram of the PLL used in AD2516X. It generates the pixel clock by using the positive HSYNC signal from the sync processor block and the divider coefficient determined by the resolution. The reference clock frequency range is between 20kHz - 150kHz and the maximum output clock frequency is 180MHz. It produces two clock signals having the ADC clock frequency and each signal can have 7.5° phase control. AD2516X is controlled entirely through serial interface, which supports two modes -12C bus and 3-wire interface. 14 TRIPLE 8-BIT ANALOG-TO-DIGITAL CONVERTER KB2516 (Preliminary) REGISTER CONFIGRATION PRE-AMP Sub Addr.
