11 / 21 page GS6042 Final Data Sheet Rev. 3 PDS-060055 May 2014 11 of 21 Proprietary and Confidential www.semtech.com 4. Detailed Description The GS6042 is a high-speed BiCMOS IC designed to automatically equalize high-bandwidth serial digital video signals. The GS6042 can equalize data rates up to 6.25Gb/s including 6G UHD-SDI, 3G SDI, HD SDI, and SD SDI serial digital signals. The GS6042 is optimized to equalize up to 80m of Belden 1694A cable at 5.94Gb/s (UHD-SDI), 210m at 2.97Gb/s (3G-SDI), 300m at 1.485Gb/s (HD-SDI), and 500m at 270Mb/s (SD-SDI). The GS6042 can be powered from a single +3.3V DC power supply, and is footprint-compatible with Semtech’s GS2974A, GS2974B, GS2984, GS2994, and GS3440 equalizers. 4.1 Serial Digital Inputs The received serial data signal is connected to the input pins (SDI/SDI) in either a differential or single-ended configuration. AC-coupling of the inputs is recommended because the SDI and SDI inputs are internally biased to approximately 1.71V. See Figure 5-1 for the recommended input applications circuit when using a single-ended 75 Ω coax cable. 4.2 Automatic (Adaptive) Cable Equalization The input signal passes through a variable gain equalizing stage, whose frequency response closely matches the inverse of the Belden 1694A cable loss characteristic for any given attached cable length within the supported ranges. The equalized signal is DC-restored, effectively restoring the logic threshold of the equalized signal to its correct level independent of shifts due to AC-coupling. 4.3 Differential Digital Data Output The digital data output signals (DDO/DDO) have a nominal output voltage swing of either 850mVppd or 425mVppd (ΔVDDO), as set by the OP_CTL pin. Table 4-1 shows the typical output common mode voltage levels (VCMOUT) related to the two output swing options and the type of output transmission termination as shown in Figure 4-1 and Figure 4-2. |
