1.8V Phase-Lock Loop Clock Driver for DDR2 SDRAM ApplicationsThe CDCUA877 is a high-performance, low-jitter, low-skew, zero-delay buffer that distributes a differential clock input pair (CK, CK) to ten differential pairs of clock outputs (Yn, Yn) and to one differential pair of feedback clock outputs (FBOUT, FBOUT). The clock outputs are controlled by the input clocks (CK, CK), the feedback clocks (FBIN, FBIN), the LVCMOS control pins (OE, OS), and the analog power input (AVDD). When OE is low, the clock outputs, except FBOUT/FBOUT, are disabled while the
1.8-V Phase Lock Loop Clock DriverThe CDCU2A877 is a high-performance, low-jitter, low-skew, zero-delay buffer that distributes a differential clock input pair (CK, CK) to 10 differential pairs of clock outputs (Yn, Yn) and to one differential pair of feedback clock outputs (FBOUT, FBOUT). The clock outputs are controlled by the input clocks (CK, CK), the feedback clocks (FBIN, FBIN), the LVCMOS control pins (OE, OS), and the analog power input (AVDD).

28-Bit to 56-Bit Registered Buffer with Address-Parity TestThis 28-bit 1:2 configurable registered buffer is designed for 1.7-V to 1.9-V VCC operation. One device per DIMM is required to drive up to 18 SDRAM loads or two devices per DIMM are required to drive up to 36 SDRAM loads.
25-Bit Configurable Registered Buffer w/Address-Parity TestThis 25-bit 1:1 or 14-bit 1:2 configurable registered buffer is designed for 1.7-V to 1.9-V VCC operation. In the 1:1 pinout configuration, only one device per DIMM is required to drive nine SDRAM loads. In the 1:2 pinout configuration, two devices per DIMM are required to drive 18 SDRAM loads.
具有地址奇偶校验的 28 位至 56 位寄存缓冲器This 28-bit 1:2 configurable registered buffer is designed for 1.7-V to 1.9-V VCC operation. One device per DIMM is required to drive up to stacked 18 SDRAM loads or two devices per DIMM are required to drive up to 36 stacked SDRAM loads.
