Package options include a plastic 52-ball VFBGA and a 40-pin MLF. ICS98ULPA877A is a zero delay buffer that distributes a differential clock input pair (CLK INT, CLK INC) to ten differential pair of clock outputs (CLKT 0:9 , CLKC 0:9 ) and one differential pair feedback clock outputs (FB OUTT, FBOUTC). The clock outputs are controlled by the input clocks (CLK INT, CLK INC), the feedback clocks (FB INT, FB INC), the LVCMOS program pins (OE, OS) and the Analog Power input (AVDD). When OE is low, the outputs (except FB OUTT/FB OUTC) are disabled while the internal PLL continues to maintain its locked-in frequency. OS (Output Select) is a program pin that must be tied to GND or V . When OS is high, OE will function as described above. When DDQ OS is low, OE has no effect on CLKT7/CLKC7 (they are free running in addition to FB OUTT/FB OUTC). When AV DD is grounded, the PLL is turned off and bypassed for test purposes. When both clock signals (CLK INT, CLK INC) are logic low, the device will enter a low power mode. An input logic detection circuit on the differential inputs, independent from the input buffers, will detect the logic low level and perform a low power state where all outputs, the feedback and the PLL are OFF. When the inputs transition from both being logic low to being differential signals, the PLL will be turned back on, the inputs and outputs will be enabled and the PLL will obtain phase lock between the feedback clock pair (FB INT, FB INC) and the input clock pair (CLK INT, CLK INC) within the specified stabilization time t . STAB The PLL in ICS98ULPA877A clock driver uses the input clocks (CLK INT, CLK INC) and the feedback clocks (FB INT, FB INC) to provide high-performance, low-skew, low-jitter output differential clocks (CLKT 0:9 , CLKC 0:9 ). ICS98ULPA877A is also able to track Spread Spectrum Clocking (SSC) for reduced EMI. 1177F12/10/09 2
