9FG1201HGLFT

DATASHEET Frequency Gearing Clock for CPU, PCIe Gen1, Gen2, & FBD Description The ICS9FG1201H follows the Intel DB1200G Rev 1.0 Differential Buffer Specification. This buffer provides 12 output clocks for CPU Host Bus, PCI-Express, or Fully Buffered DIMM applications. The outputs are configured with two groups. Both groups (DIF 9:0) and (DIF 11:10) can be equal to or have a gear ratio to the input clock. A differential CPU clock from a CK410B or CK410B+ main clock generator, such as the ICS932S421, drives the ICS9FG1201. The ICS9FG1201H can provide outputs up to 400MHz ICS9FG1201H Features/Benefits • • • • • • • • Drives 2 channels of 4 FBDIMMs (total of 8 FBDIMMs) Power up default is all outputs in 1:1 mode DIF_(9:0) can be “gear-shifted” from the input CPU Host Clock DIF_(11:10) can be “gear-shifted” from the input CPU Host Clock Spread spectrum compatible Supports output clock frequencies up to 400 MHz 8 Selectable SMBus addresses SMBus address determines PLL or Bypass mode Key Specifications • • • DIF output cycle-to-cycle jitter < 50ps DIF output-to-output skew < 50ps within a group DIF output-to-output skew < 100ps across all outputs • • 56-pin SSOP/TSSOP package RoHS compliant packaging Functional Block Diagram OE# SPREAD COMPATIBLE PLL GEAR SHIFT LOGIC STOP LOGIC 2 DIF(11:10) OE(9:0)# 10 CLK_IN CLK_IN# SPREAD COMPATIBLE PLL GEAR SHIFT LOGIC STOP LOGIC 10 DIF(9:0) HIGH_BW# FS_A_410 VTT_PWRGD#/PD SMB_A0 SMB_A1 SMB_A2_PLLBYP# SMBDAT SMBCLK CONTROL LOGIC IREF IDTTM/ICSTM Frequency Gearing Clock for CPU, PCIe Gen1, Gen2, & FBD 1371F — 09/23/09 1 ICS9FG1201H Frequency Gearing Clock for CPU, PCIe Gen1, Gen2, & FBD Pin Configuration HIGH_BW# CLK_IN CLK_IN# SMB_A0 OE0# DIF_0 DIF_0# OE1# DIF_1 DIF_1# VDD GND DIF_2 DIF_2# OE2# DIF_3 DIF_3# OE3# DIF_4 DIF_4# OE4# VDD GND DIF_5 DIF_5# OE5# SMB_A1 SMBDAT 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 56 55 54 53 52 51 50 49 48 47 46 45 44 43 42 41 40 39 38 37 36 35 34 33 32 31 30 29 VDDA GNDA IREF OE10_11# DIF_11 DIF_11# VDD GND DIF_10 DIF_10# FS_A_410 VTT_PWRGD#/PD OE9# DIF_9 DIF_9# OE8# DIF_8 DIF_8# VDD GND DIF_7 DIF_7# OE7# DIF_6 DIF_6# OE6# SMB_A2_PLLBYP# SMBCLK 56-pin SSOP & TSSOP Functionality Table DIF_(9:0) Output DIF_(11:10) Output MHz MHz 1 100.00 100.00 1 133.33 133.33 1 166.66 166.66 1 RESERVED 0 200.00 200.00 200.00 0 266.66 266.66 266.66 0 333.33 333.33 333.33 0 400.00 400.00 400.00 1.

Input to output skew is measured at the first output edge following the corresponding input. 3. All Bypass Mode Input-to-Output specs refer to the timing between an input edge and the specific output edge created by it. 4. This parameter is deterministic for a given device 5. Measured with scope averaging on to find mean value. 6. Long-term variation from nominal of input-to-output skew over temperature and voltage for a single device. 7. This parameter is measured at the outputs of two separate 9FG1201H devices driven by a single CK410B+. The 9FG1201H must be set to high bandwidth. Differential phase jitter is the accumulation of the phase jitter not shared by the outputs (eg. not including the affects of spread spectrum). Target ranges of consideration are agents with BW of 1-22MHz and 11-33MHz. 8. t is the period of the input clock 9. Differential spread spectrum tracking error is the difference in spread spectrum tracking between two 9FG1201H devices This parameter is measured at the outputs of two separate 9FG1201H devices driven by a single CK410B+ in Spread Spectrum mode. The 9FG1201H must set to high bandwidth. The spread spectrum characterisitics are : maximum of 0.5%, 30 to 33KHz modulation frequency, linear profile. 10. This parameter is an absolute value. It is not a double-sided figure. 11. Measured as maximum pass band gain. At frequencies within the loop BW, highest point of magnification is called PLL jitter peaking. 12. Guaranteed by design and characterization, not 100% tested in production. 13. Measured at 3 db down or half power point.
