outputs of the chipset. If needed, clock device register

changes are normally made upon system initialization. The

interface can also be used during system operation for power

management functions. Table 3 summarizes the control

functions of the serial data interface.

Serial Data Interface

The W150 features a two-pin, serial data interface that can be

used to configure internal register settings that control

particular device functions. Upon power-up, the W150

initializes with default register settings, therefore the use of this

serial data interface is optional. The serial interface is

write-only (to the clock chip) and is the dedicated function of

device pins SDATA and SCLOCK. In motherboard applica-

tions, SDATA and SCLOCK are typically driven by two logic

Operation

Data is written to the W150 in eleven bytes of eight bits each.

Bytes are written in the order shown in Table 4.

Table 3. Serial Data Interface Control Functions Summary

Control Function

Description

Common Application

Clock Output Disable Any individual clock output(s) can be disabled.

Disabled outputs are actively held LOW.

Unused outputs are disabled to reduce EMI and

system power. Examples are clock outputs to

unused PCI slots.

CPU Clock

Provides CPU/PCI frequency selections through

For alternate microprocessors and power

management options. Smooth frequency transition

allowsCPUfrequencychangeundernormalsystem

operation.

Frequency Selection software. Frequency is changed in a smooth and

controlled fashion.

Spread Spectrum

Enabling

Enables or disables spread spectrum clocking.

Puts clock output into a high-impedance state.

For EMI reduction.

Output Three-state

Test Mode

Production PCB testing.

All clock outputs toggle in relation to X1 input,

internal PLL is bypassed. Refer to Table 5.

(Reserved)

Reserved function for future device revision or

production device testing.

No user application. Register bit must be written as

Table 4. Byte Writing Sequence

Byte

Sequence Byte Name Bit Sequence

Byte Description

Slave Address 11010010

Commands the W150 to accept the bits in Data Bytes 0–7 for internal register

configuration. Since other devices may exist on the same common serial data bus,

it is necessary to have a specific slave address for each potential receiver. The

slave receiver address for the W150 is 11010010. Register setting will not be made

if the Slave Address is not correct (or is for an alternate slave receiver).

Command

Code

Don’t Care

Unused by the W150, therefore bit values are ignored (“Don’t Care”). This byte

must be included in the data write sequence to maintain proper byte allocation. The

Command Code Byte is part of the standard serial communication protocol and

may be used when writing to another addressed slave receiver on the serial data

bus.

Byte Count

Unused by the W150, therefore bit values are ignored (“Don’t Care”). This byte

must be included in the data write sequence to maintain proper byte allocation. The

Byte Count Byte is part of the standard serial communication protocol and may be

used when writing to another addressed slave receiver on the serial data bus.
