Clock Generator
ICS841S01
DATA SHEET
General Description
The ICS841S01 is a PLL-based clock generator specifically
designed for PCI_Express™ Clock Generation applications. This
device generates a 100MHz HCSL clock. The device offers a HCSL
(Host Clock Signal Level) clock output from a clock input reference of
25MHz. The input reference may be derived from an external source
or by the addition of a 25MHz crystal to the on-chip crystal oscillator.
An external reference may be applied to the XTAL_IN pin with the
XTAL_OUT pin left floating.
The device offers spread spectrum clock output for reduced EMI
applications. An I
2
C bus interface is used to enable or disable spread
spectrum operation as well as select either a down spread value of
-0.35% or -0.5%.
Features
One 0.7V current mode differential HCSL output pair
Crystal oscillator interface: 25MHz
Output frequency: 100MHz
RMS period jitter: 3ps (maximum)
Cycle-to-cycle jitter: 35ps (maximum)
I
2
C support with readback capabilities up to 400kHz
Spread Spectrum for electromagnetic interference (EMI) reduction
3.3V operating supply mode
0°C to 70°C ambient operating temperature
Available in both standard (RoHS 5) and lead-free (RoHS 6)

CLOCK GENERATOR
Serial Data Interface
To enhance the flexibility and function of the clock synthesizer, a
two-signal serial interface is provided. Through the Serial Data
Interface, various device functions, such as individual clock output
buffers, can be individually enabled or disabled. The registers
associated with the Serial Data Interface initialize to their default
setting upon power-up, and therefore, use of this interface is optional.
Clock device register changes are normally made upon system
initialization, if any are required. The interface cannot be used during
system operation for power management functions.
Data Protocol
The clock driver serial protocol accepts byte write, byte read, block
write, and block read operations from the controller. For block
write/read operation, the bytes must be accessed in sequential order
from lowest to highest byte (most significant bit first) with the ability to
stop after any complete byte has been transferred. For byte write and
byte read operations, the system controller can access individually
indexed bytes. The offset of the indexed byte is encoded in the
command code, as described in
Table 3A.
The block write and block read protocol is outlined in
Table 3B,
while
Table 3C
outlines the corresponding byte write and byte read
protocol. The slave receiver address is 11010010 (D2h).
