Integrated Circuit Systems, Inc. ICS9150-01 Pentium Pro™ and SDRAM Frequency Generator General Description The ICS9150-01 generates all clocks required for high speed RISC or CISC microprocessor systems such as Intel PentiumPro. Two different reference frequency multiplying factors are externally selectable with smooth frequency transitions. An output enable is provided for testability.

REF0 The REF Output is a fixed frequency Clock that runs at the same frequency as the Input Reference Clock X1 or the Crystal (typically 14.31818MHz) attached across X1 and X2. This pin operates at 3.3V volts. Clocks from the listed buffers that it supplies will have a voltage swing from Ground to this level. For the actual guaranteed high and low voltage levels for the Clocks, please consult the DC parameter table in this data sheet. PCICLK_F This Output is equal to PCICLK(0:5) and is FREE RUNNING, and will not be stopped by PCI_STP#. PCICLK (0:5) These Output Clocks generate all the PCI timing requirements for a Pentium/Pro based system. They conform to the current PCI specification. They run at 1/2 CPU frequency. VDDL1,2 This is the power supplies for the CPUCLK and IOAPCI output buffers. The voltage level for these outputs may be 2.5 or 3.3volts. Clocks from the buffers that each supplies will have a voltage swing from Ground to this level. For the actual Guaranteed high and low voltage levels of these Clocks, please consult the DC parameter table in this Data Sheet. FS0 This Input pin controls the frequency of the Clocks at the CPU, PCICLK and SDRAM output pins. If a logic “1” value is present on this pin, the 66.6 MHz Clock will be selected. If a logic “0” is used, the 60MHz frequency will be selected. (This is the Power Management Mode) GND This is the power supply ground (common or negative) return pin for the internal core logic and all the output buffers. MODE This Input pin is used to select the Input function of the I/O pins. An active Low will place the I/O pins in the Input mode and enable those stop clock functions. (This is the Power Management Mode) X1 This input pin serves one of two functions. When the device is used with a Crystal, X1 acts as the input pin for the reference signal that comes from the discrete crystal. When the device is driven by an external clock signal, X1 is the device input pin for that reference clock. This pin also implements an internal Crystal loading capacitor that is connected to ground. See the data tables for the value of this capacitor. CPU_STOP# This is a synchronous active Low Input pin used to stop the CPUCLK clocks in an active low state. All other Clocks including SDRAM clocks will continue to run while this function is enabled. The CPUCLK’s will have a turn ON latency of at least 3 CPU clocks. This input pin only valid when MODE=0 (Power Management Mode) X2 This Output pin is used only when the device uses a Crystal as the reference frequency source. In this mode of operation, X2 is an output signal that drives (or excites) the discrete Crystal. The X2 pin will also implement an internal Crystal loading capacitor that is connected to ground. See the Data Sheet for the value of this capacitor. PCI_STOP# This is a synchronous active Low Input pin used to stop the PCICLK clocks in an active low state. It will not effect PCICLK_F nor any other outputs. This input pin only valid when MODE=0 (Power Management Mode) CPUCLK (0:4) These Output pins are the Clock Outputs that drive processor and other CPU related circuitry that requires clocks which are in tight skew tolerance with the CPU clock. The voltage swing of these Clocks are controlled by the Voltage level applied to the VDDL2 pin of the device. See the Functionality Table for a list of the specific frequencies that are available for these Clocks and the selection codes to produce them. I2C The SDATA and SCLOCK Inputs are use to program the device. The clock generator is a slave-receiver device in the I2C protocol. It will allow read-back of the registers. See configuration map for register functions. The I2C specification in Philips I2C Peripherals Data Handbook (1996) should be followed. SDRAM(0:15) These Output Clocks are use to drive Dynamic RAM’s and are low skew copies of the CPU Clocks. The voltage swing of the SDRAM’s output is controlled by the supply voltage that is applied to VDD3 of the device, operates at 3.3 volts. IOAPIC (0:2) These Outputs are fixed frequency Output Clocks that run at the Reference Input (typically 14.31818MHz) . Its voltage level swing is controlled by VDDL1 and may operate at 2.5 or 3.3volts. 4 ICS9150-01 General I2C serial interface information For the clock generator to be addressed by an I2C controller, the following address must be sent as a start sequence, with an acknowledge bit between each byte. A. Clock Generator Address (7 bits) A(6:0) & R/W# ACK + 8 bits dummy command code ACK + 8 bits dummy Byte count ACK Then Byte 0, 1, 2, etc in sequence until STOP. D2(H) The clock generator is a slave/receiver I2C component. It can "read back "(in Philips I2C protocol) the data stored in the latches for verification. (set R/W# to 1 above). There is no BYTE count supported, so it does not meet the Intel SMB PIIX4 protocol. B. Clock Generator Address (7 bits) A(6:0) & R/W# ACK Byte 0 ACK Byte 1 ACK Byte 0, 1, 2, etc in sequence until STOP. D3(H) C. The data transfer rate supported by this clock generator is 100K bits/sec (standard mode) D. The input is operating at 3.3V logic levels. E. The data byte format is 8 bit bytes. F. To simplify the clock generator I2C interface, the protocol is set to use only block writes from the controller. The bytes must be accessed in sequential order from lowest to highest byte with the ability to stop after any complete byte has been transferred. The Command code and Byte count shown above must be sent, but the data is ignored for those two bytes. The data is loaded until a Stop sequence is issued. G. In the power down mode (PWR_DWN# Low), the SDATA and SCLK pins are tristated and the internal data latches maintain all prior programming information. H. At power-on, all registers are set to a default condition.

Clock on latency is defined from when the clock enable goes active to when the first valid clock comes out of the device. 2. Clock off latency is defined from when the clock enable goes inactive to when the last clock is driven low out of the device. 7 ICS9150-01 CPU_STOP# Timing Diagram CPUSTOP# is an asychronous input to the clock synthesizer. It is used to turn off the CPUCLKs for low power operation. CPU_STOP# is synchronized by the ICS9150-01. The minimum that the CPUCLK is enabled (CPU_STOP# high pulse) is 100 CPUCLKs. All other clocks will continue to run while the CPUCLKs are disabled. The CPUCLKs will always be stopped in a low state and start in such a manner that guarantees the high pulse width is a full pulse. CPUCLK on latency is less than 4 CPUCLKs and CPUCLK off latency is less than 4 CPUCLKs. Notes: 1. All timing is referenced to the internal CPUCLK. 2. CPU_STOP# is an asynchronous input and metastable conditions may exist. This signal is synchronized to the CPUCLKs inside the ICS9150-01. 3. All other clocks continue to run undisturbed. 4. PCI_STOP# is shown in a high (true) state. 8 ICS9150-01 PCI_STOP# Timing Diagram PCI_STOP# is an asynchronous input to the ICS9150-01. It is used to turn off the PCICLK (0:5) clocks for low power operation. PCI_STOP# is synchronized by the ICS9150-01 internally. The minimum that the PCICLK (0:5) clocks are enabled (PCI_STOP# high pulse) is at least 10 PCICLK (0:5) clocks. PCICLK (0:5) clocks are stopped in a low state and started with a full high pulse width guaranteed. PCICLK (0:5) clock on latency cycles are only one rising PCICLK clock off latency is one PCICLK clock. Notes: 1. All timing is referenced to the Internal CPUCLK (defined as inside the ICS9150 device.) 2. PCI_STOP# is an asynchronous input, and metastable conditions may exist. This signal is required to be synchronized inside the ICS9150. 3. All other clocks continue to run undisturbed. 4. CPU_STOP# is shown in a high (true) state. 9 ICS9150-01 Absolute Maximum Ratings Supply Voltage . . . . . . . . . . . . . . . . . . . . . . . . . . 7.0 V Logic Inputs . . . . . . . . . . . . . . . . . . . . . . . . . . . .
