6 / 77 page ![]() GS6151 Final Data Sheet Rev.4 PDS-060389 August 2015 6 of 77 Semtech Proprietary & Confidential www.semtech.com 1.2 Pin Descriptions Table 1-1: GS6151 Pin Descriptions Pin Number Name Type Description 1, 2 DDI0, DDI0 Input Serial Digital Differential Input 0. 3 GND Power Input channel isolation. Connect to ground or leave unconnected. 4, 5 DDI1, DDI1 Input Serial Digital Differential Input 1. 6GPIO0 Digital Input/Output Multi-function Control/Status Input/Output 0. Signal options are: LOS (output; default) LOCKED LBR_HBR RATE_DET0 RATE_DET1 RATE_DET2 LOCKED_270M LOCKED_1G485 LOCKED_2G97 LOCKED_5G94 RATE_CHANGE DDO0_DISABLE DDO1_DISABLE This pin is configured using the GPIO0_SELECT and GPIO0_IO_SELECT bits in the GPIO_CONTROL_REG_0 register. 7GPIO1 Digital Input/Output Multi-function Control/Status Input/Output 1. Signal options are: LOS LOCKED (output; default) LBR_HBR RATE_DET0 RATE_DET1 RATE_DET2 LOCKED_270M LOCKED_1G485 LOCKED_2G97 LOCKED_5G94 RATE_CHANGE DDO0_DISABLE DDO1_DISABLE This pin is configured using the GPIO1_SELECT and GPIO1_IO_SELECT bits in the GPIO_CONTROL_REG_0 register. 8 DDI_SEL/STROBE Digital Input Input selection control. Used to select the high-speed input for processing through the device. Refer to Table 4-2 for details on input selection. 9 XTAL_CLK_IN Input Reference Crystal Pin/27MHz clock input. Connect to an external circuit as shown in Figure 6-1: GS6151 Typical Application Circuit or to a digital clock source (XTAL_BUF_OUT of another GS6150, GS6151, GS6152, or a 27MHz clock output from another device). Connect to ground if operating referenceless. |
