10 / 102 page GS4901B/GS4900B SD Clock and Timing Generator with GENLOCK Data Sheet 37703 - 4 December 2009 10 of 102 9 CORE_GND – Power Supply Ground connection for core and I/O. Solder to the ground plane of the application board. NOTE: The CORE_GND pin should be soldered to the same main ground plane as the exposed ground pad on the bottom of the device. 10 ANALOG_VDD – Power Supply Most positive power supply connection for the analog input block. Connect to +1.8V DC. 11, 20, 63NC – – Do not connect. 12 ANALOG_GND – Power Supply Ground connection for the analog input block. Connect to GND. 13 AUD_PLL_GND (GS4901B only) –Power Supply Ground connection for the audio clock synthesis internal block. Connect to GND. ANALOG_GND (GS4900B only) –Power Supply Ground connection for the analog input block. Connect to GND. 14 AUD_PLL_VDD (GS4901B only) –Power Supply Most positive power supply connection for the audio clock synthesis internal block. Connect to +1.8V DC. ANALOG_GND (GS4900B only) –Power Supply Ground connection for the analog input block. Connect to GND. 15 10FID Non Synchronous Input REFERENCE SIGNAL INPUT Signal levels are LVCMOS/LVTTL compatible. The 10FID external reference signal is applied to this pin by the application layer. 10FID defines the field in which the video and audio clock phase relationship is defined according to SMPTE 318-M. It is also used to define a 3:2 video cadence. NOTE: If the input reference format does not include a 10 Field ID signal, this pin should be held LOW. See Section 3.4.2 on page 42. 16 HSYNC Non Synchronous Input REFERENCE SIGNAL INPUT Signal levels are LVCMOS/LVTTL compatible. The HSYNC external reference signal is applied to this pin by the application layer. When the GS4901B/GS4900B is operating in Genlock mode, the device senses the polarity of the HSYNC input automatically, and references to the leading edge. This signal must adhere to one of the 36 defined video standards supported by the device. In this mode of operation, the HSYNC input provides a horizontal scanning reference signal. The HSYNC signal may have analog timing, such as from a sync separator, or may be digital such as from an SDI deserializer. Section 1.4 on page 19 describes the 36 video formats recognized by the GS4901B/GS4900B. Table 1-1: Pin Descriptions (Continued) Pin Number Name Timing Type Description |
