http://www.xiaoyu163.com IC DESCRIPTION - 1/12 (SSI33P3721)-1/2 3 7 63 1515 0 Pin No. Pin Name Description DVDRFP RF SIGNAL INPUTS: Differential RF signal attenuator input pins. DVDRFN CD PHOTO DETECTOR INTERFACE INPUTS: Inputs from the CD photo detector outputs. PHOTO DETECTOR NTERFACE INPUTS: AC coupled inputs for the DPD from the main beam Photo detector matrix outputs.
Page 49 http://www.xiaoyu163.com IC DESCRIPTION - 1/12 (SSI33P3721)-2/2 3 7 63 1515 0 Pin No. Pin Name Description PULL-IN SIGNAL OUTPUT: The summing signal output of A,B,C,D inputs for mirror detection. Reference to VCI. DEFECT OUTPUT: Pseudo CMOS output. When defect is detected, the DFT output goes high. Also the servo AGC output can be monitored at this DFT pin, when CAR bit7-4 is ‘0011’.
Page 50 http://www.xiaoyu163.com IC DESCRIPTION - 2/12 (GM72V161621ET-7)-1/2 3 7 63 1515 0 Pin No. Pin Name Description – 3.3 V is applied. (VCC is for the internal circuit.) Data is input and ouput from these pins. These pins are the same as those of a conventional DRAM.
Page 51 http://www.xiaoyu163.com IC DESCRIPTION - 2/12 (GM72V161621ET-7)-2/2 3 7 63 1515 0 Pin No. Pin Name Description This pin determines whether or not the next CLK is valid. If CKE is High, the next CLK rising edge is valid. If CKE is Low, the next CLK rising edge is invalid. This pin is used for power- down and clock suspend modes.
Page 52 http://www.xiaoyu163.com IC DESCRIPTION - 3/12 (PLL1700E)-1/1 3 7 63 1515 0 Pin No. Pin Name Description Latch Enable for Software Mode/Sampling Rate Selection for Hardware Mode.
