14.318–150 MHz I2C 1:10 clock buffer
PCK2001M
FEATURES
• 175 ps skew outputs
• Individual clock output enable/disable via I C
• Mobile (reduced pincount) version of PCK2001
2
• Typically used to support two SDRAM DIMMs
• 28-pin SSOP package
• Same general features as PCK2001
DESCRIPTION
The PCK2001M is a 1–10 fanout buffer used for 133/100 MHz CPU,
66/33 MHz PCI, 14.318 MHz REF, or 133/100/66 MHz SDRAM
clock distribution. 10 outputs are typically used to support up to
2 SDRAM DIMMs commonly found in laptop or mobile applications.
The PCK2001M has the same features and operating characteristics
of the PCK2001 and is available in the SSOP 28 pin package.
• See PCK2001 for 48-pin 1-18 buffer part supporting up to
4 SDRAM DIMMs
• Optimized for 66 MHz, 100 MHz and 133 MHz operation

I C CONSIDERATIONS
2
2
I C has been chosen as the serial bus interface to control the PCK2001M. I C was chosen to support the JEDEC proposal JC-42.5 168-Pin
2
Unbuffered SDRAM DIMM. All vendors are required to determine the legal issues associated with the manufacture of I C devices.
1) Address assignment: The clock driver in this specification uses the single, 7-bit address shown below. All devices can use the address if only
2
one master clock driver is used in a design. The address can be re-used for the CKBF device if no other conflicting I C clock driver is used in
the system.
The following address was confirmed by Philips on 09/04/96.

A5
A4
A3
A2
A1
A0
R/W#
0

0

0
0

2
NOTE: The R/W# bit is used by the I C controller as a data direction bit. A ‘zero’ indicates a transmission (WRITE) to the clock device. A ‘one’
indicates a request for data (READ) from the clock driver. Since the definition of the clock buffer only allows the controller to WRITE data; the
R/W# bit of the address will always be seen as ‘zero’. Optimal address decoding of this bit is left to the vendor.
2) Options: It is our understanding that metal mask options and other pinouts of this type of clock driver will be allowed to use the same address
2
as the original CKBF device. I C addresses are defined in terms of function (master clock driver) rather than form (pinout, and option).
3) Slave/Receiver: The clock driver is assumed to require only slave/receiver functionality. Slave/transmitter functionality is optional.
4) Data Transfer Rate: 100 kbits/s (standard mode) is the base functionality required. Fast mode (400 kbits/s) functionality is optional.
2
5) Logic Levels: I C logic levels are based on a percentage of V for the controller and other devices on the bus. Assume all devices are
DD
based on a 3.3 Volt supply.
6) Data Byte Format: Byte format is 8 Bits as described in the following appendices.
2
7) Data Protocol: To simplify the clock I C interface, the clock driver serial protocol was specified 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
2
transferred. Indexed bytes are not allowed. However, the SMBus controller has a more specific format than the generic I C protocol.
2
The clock driver must meet this protocol which is more rigorous than previously stated I C protocol. Treat the description from the viewpoint of
controller. The controller ‘‘writes” to the clock driver and if possible would ‘‘read” from the clock driver (the clock driver is a slave/receiver only
and is incapable of this transaction.)
‘‘The block write begins with a slave address and a write condition. After the command code the host (controller) issues a byte count which
describes how many more bytes will follow in the message. If the host had 20 bytes to send, the first byte would be the number 20 (14h),
followed by the 20 bytes of data. The byte count may not be 0. A block write command is allowed to transfer a maximum of 32 data bytes.”

NOTE: The acknowledgement bit is returned by the slave/receiver (the clock driver).
Consider the command code and the byte count bytes required as the first two bytes of any transfer. The command code is software
programmable via the controller, but will be specified as 0000 0000 in the clock specification. The byte count byte is the number of additional
bytes required to transfer, not counting the command code and byte count bytes. Additionally, the byte count byte is required to be a minimum of
1 byte and a maximum of 32 bytes to satisfy the above requirement.

0110 Reads first six bytes (byte 0, 1, 2, 3, 4, 5 in order)
0111 Reads first seven bytes (byte 0, 1, 2, 3, 4, 5, 6 in order)
0000 Max byte count supported = 32
A transfer is considered valid after the acknowledge bit corresponding to the byte count is read by the controller. The serial controller interface
can be simplified by discarding the information in both the command code and the byte count bytes and simply reading all the bytes that are
sent to the clock driver after being addressed by the controller. It is expected that the controller will not provide more bytes than the clock driver
can handle. A clock vendor may choose to discard any number of bytes that exceed the defined byte count.
8) Clock stretching: The clock device must not hold/stretch the SCLOCK or SDATA lines low for more than 10 mS. Clock stretching is
discouraged and should only be used as a last resort. Stretching the clock/data lines for longer than this time puts the device in an error/time-out
mode and may not be supported in all platforms. It is assumed that all data transfers can be completed as specified without the use of
clock/data stretching.
9) General Call: It is assumed that the clock driver will not have to respond to the ‘‘general call.”
2
10) Electrical Characteristics: All electrical characteristics must meet the standard mode specifications found in section 15 of the I C specification.
a) Pull-Up Resistors: Any internal resistors pull-ups on the SDATA and SCLOCK inputs must be stated in the individual datasheet. The use of
internal pull-ups on these pins of below 100 k is discouraged. Assume that the board designer will use a single external pull-up resistor for each
2
2
line and that these values are in the 5 – 6 k Ohm range. Assume one I C device per DIMM (serial presence detect), one I C controller, one
2
clock driver plus one/two more I C devices on the platform for capacitive loading purposes.
2
(b) Input Glitch Filters: Only fast mode I C devices require input glitch filters to suppress bus noise. The clock driver is specified as a standard
mode device and is not required to support this feature.
11) PWR DWN#: If a clock driver is placed in PWR DWN# mode, the SDATA and SCLK inputs must be 3-Stated and the device must retain all
2
programming information. I current due to the I C circuitry must be characterized and in the data sheet.

SERIAL CONFIGURATION MAP
The serial bits will be read by the clock buffer in the following order:
Byte 0 – Bits 7, 6, 5, 4, 3, 2, 1, 0
Byte 1 – Bits 7, 6, 5, 4, 3, 2, 1, 0
Byte 2 – Bits 7, 6, 5, 4, 3, 2, 1, 0
All unused register bits (Reserved and N/A) should be desined as “Don’t Care”. It is expected that the controller will force all of these bits to a
“0” level.
All register bits labeled “Initialize to 0” must be written to zero during intialization. Failure to do so may result in a higher than normal operating
current. The controller will read back the last written value.

Definitions
Short-form specification — The data in a short-form specification is extracted from a full data sheet with the same type number and title. For
detailed information see the relevant data sheet or data handbook.
Limiting values definition — Limiting values given are in accordance with the Absolute Maximum Rating System (IEC 134). Stress above one
or more of the limiting values may cause permanent damage to the device. These are stress ratings only and operation of the device at these or
at any other conditions above those given in the Characteristics sections of the specification is not implied. Exposure to limiting values for extended
periods may affect device reliability.
Application information — Applications that are described herein for any of these products are for illustrative purposes only. Philips
Semiconductors make no representation or warranty that such applications will be suitable for the specified use without further testing or
modification.
