6 / 27 page  GS4915 ClockCleaner™ Data Sheet 39145 - 5 June 2009 6 of 27 1.2 Pin Descriptions Table 1-1: Pin Descriptions Pin Number Name Timing Type Description 1 REG_VDD – Power Positive power supply connection for the internal voltage regulator. Connect to filtered +3.3V DC. 2, 6, 9, 26, 30, 31, 40 AGND – Power Ground connection for analog blocks and IOs. Connect to clean analog GND. 3 PD_VDD – Power Positive power supply connection for the phase detector. Connect to filtered +1.8V DC. 4, 5 CLKIN, CLKIN – Input CLOCK SIGNAL INPUTS Signal levels are CML/LVDS compatible. A differential clock input signal is applied to these pins. 7 IN_VDD – Power Positive power supply connection for the single-ended and differential input clock buffers. Supplies CLKIN_SE. Connect to filtered +1.8V DC. 8 CLKIN_SE – Input CLOCK SIGNAL INPUT Signal levels are LVCMOS compatible. A single-ended video clock input signal is applied to this pin. 10 RESET Non synchronous Input CONTROL SIGNAL INPUT Signal levels are LVCMOS/LVTTL compatible. See Section 3.8.1 for operation. 11 IPSEL Non synchronous Input CONTROL SIGNAL INPUT Signal levels are LVCMOS compatible. Selects which input clock is cleaned by the device. See Section 3.2.3 for operation. 12, 20, 22 GND – Power Ground connection for digital blocks and IO’s. Connect to GND. 13 BYPASS Non synchronous Input CONTROL SIGNAL INPUT Signal levels are LVCMOS compatible. See Manual Bypass Section 3.4.2. 14 AUTOBYPASS Non synchronous Input CONTROL SIGNAL INPUT Signal levels are LVCMOS compatible. Selects the bypass mode of the device. See Manual Bypass Section 3.4.2. 15 D_VDD – Power Positive power supply connection for digital block. Connect to filtered +1.8V DC. The digital block includes pins 10 - 21. 17, 16 FCTRL1, FCTRL0 Non synchronous Input CONTROL SIGNAL INPUTS Signal levels are LVCMOS compatible. Selects the frequency mode of the device. See Section 3.4.1 for operation. |
