MOTOROLA MC88LV915

SEMICONDUCTOR TECHNICAL DATA
The MC88LV915T Clock Driver utilizes phase–locked loop technology
to lock its low skew outputs’ frequency and phase onto an input reference
clock. It is designed to provide clock distribution for high performance
PC’s and workstations.
The PLL allows the high current, low skew outputs to lock onto a single
clock input and distribute it with essentially zero delay to multiple
components on a board. The PLL also allows the MC88LV915T to
multiply a low frequency input clock and distribute it locally at a higher
(2X) system frequency. Multiple 88LV915’s can lock onto a single
reference clock, which is ideal for applications when a central system
clock must be distributed synchronously to multiple boards (see Figure 4
on Page 9).
LOW SKEW CMOS
PLL CLOCK DRIVER
Five “Q” outputs (Q0–Q4) are provided with less than 500 ps skew between their rising edges. The Q5 output is inverted (180°
phase shift) from the “Q” outputs. The 2X_Q output runs at twice the “Q” output frequency, while the Q/2 runs at 1/2 the “Q”
frequency.
The VCO is designed to run optimally between 20 MHz and the 2X_Q Fmax specification. The wiring diagrams in Figure 2 detail
the different feedback configurations which create specific input/output frequency relationships. Possible frequency ratios of the
“Q” outputs to the SYNC input are 2:1, 1:1, and 1:2.
The FREQ_SEL pin provides one bit programmable divide–by in the feedback path of the PLL. It selects between divide–by–1
and divide–by–2 of the VCO before its signal reaches the internal clock distribution section of the chip (see the block diagram on
page 2). In most applications FREQ_SEL should be held high (÷1). If a low frequency reference clock input is used, holding
FREQ_SEL low (÷2) will allow the VCO to run in its optimal range (>20MHz).
In normal phase–locked operation the PLL_EN pin is held high. Pulling the PLL_EN pin low disables the VCO and puts the
88LV915T in a static “test mode”. In this mode there is no frequency limitation on the input clock, which is necessary for a low
frequency board test environment. The second SYNC input can be used as a test clock input to further simplify board–level testing
(see detailed description on page 11).
Pulling the OE/RST pin low puts the clock outputs 2X_Q, Q0–Q4, Q5 and Q/2 into a high impedance state (3–state). After the
OE/RST pin goes back high Q0–Q4, Q5 and Q/2 will be reset in the low state, with 2X_Q being the inverse of the selected SYNC
input. Assuming PLL_EN is low, the outputs will remain reset until the 88LV915 sees a SYNC input pulse.
A lock indicator output (LOCK) will go high when the loop is in steady–state phase and frequency lock. The LOCK output will go
low if phase–lock is lost or when the PLL_EN pin is low. The LOCK output will go high no later than 10ms after the 88LV915 sees a
SYNC signal and full 5V VCC.

Timing Notes:
• The MC88LV915T aligns rising edges of the FEEDBACK input and SYNC input, therefore the SYNC input
does not require a 50% duty cycle.
• All skew specs are measured between the VCC/2 crossing point of the appropriate output edges.All skews
are specified as ‘windows’, not as a ± deviation around a center point.
• If a “Q” output is connected to the FEEDBACK input (this situation is not shown), the “Q” output frequency
would match the SYNC input frequency, the 2X_Q output would run at twice the SYNC frequency, and the
Q/2 output would run at half the SYNC frequency.

A SEPARATE ANALOG POWER SUPPLY IS NOT NECESSARY AND

IS ALL THAT IS NECESSARY TO USE THE MC88LV915T IN A NORMAL
DIGITAL ENVIRONMENT.
Figure 3. Recommended Loop Filter and Analog Isolation Scheme for the MC88LV915T
Notes Concerning Loop Filter and Board Layout Issues
1. Figure 3 shows a loop filter and analog isolation scheme
which will be effective in most applications. The following
guidelines should be followed to ensure stable and
jitter–free operation:
The purpose of the bypass filtering scheme shown in
Figure 3 is to give the 88LV915T additional protection
from the power supply and ground plane transients that
can occur in a high frequency, high speed digital system.
1a.All loop filter and analog isolation components should be
tied as close to the package as possible. Stray current
passing through the parasitics of long traces can cause
undesirable voltage transients at the RC1 pin.
1c.There are no special requirements set forth for the loop
filter resistors (1MΩ and 330Ω). The loop filter capacitor
(0.1µF) can be a ceramic chip capacitior, the same as a
standard bypass capacitor.
1b.The 47Ω resistors, the 10µF low frequency bypass
capacitor, and the 0.1µF high frequency bypass capacitor
form a wide bandwidth filter that will minimize the
88LV915T’s sensitivity to voltage transients from the
system digital VCC supply and ground planes. This filter
will typically ensure that a 100mV step deviation on the
digital VCC supply will cause no more than a 100pS phase
deviation on the 88LV915T outputs. A 250mV step
deviation on VCC using the recommended filter values
should cause no more than a 250pS phase deviation; if a
25µF bypass capacitor is used (instead of 10µF) a 250mV
VCC step should cause no more than a 100pS phase
deviation.
1d.The 1M reference resistor injects current into the internal
charge pump of the PLL, causing a fixed offset between
the outputs and the SYNC input. This also prevents
excessive jitter caused by inherent PLL dead–band. If the
VCO (2X_Q output) is running above 40MHz, the 1MΩ
resistor provides the correct amount of current injection
into the charge pump (2–3µA). For the TFN55, 70 or 100,
if the VCO is running below 40MHz, a 1.5MΩ reference
resistor should be used (instead of 1MΩ).
2. In addition to the bypass capacitors used in the analog
filter of Figure 3, there should be a 0.1µF bypass
capacitor between each of the other (digital) four VCC pins
and the board ground plane. This will reduce output
switching noise caused by the 88LV915T outputs, in
addition to reducing potential for noise in the ‘analog’
section of the chip. These bypass capacitors should also
be tied as close to the 88LV915T package as possible.
If good bypass techniques are used on a board design
near components which may cause digital VCC and
ground noise, the above described VCC step deviations
should not occur at the 88LV915T’s digital VCC supply.

MC88LV915T System Level Testing Functionality
3–state functionality has been added to the 100MHz version of the MC88LV915T to ease system board testing. Bringing the
OE/RST pin low will put all outputs (except for LOCK) into the high impedance state. As long as the PLL_EN pin is low, the
Q0–Q4, Q5, and the Q/2 outputs will remain reset in the low state after the OE/RST until a falling SYNC edge is seen. The 2X_Q
output will be the inverse of the SYNC signal in this mode. If the 3–state functionality will be used, a pull–up or pull–down resistor
must be tied to the FEEDBACK input pin to prevent it from floating when the fedback output goes into high impedance.
With the PLL_EN pin low the selected SYNC signal is gated directly into the internal clock distribution network, bypassing
and disabling the VCO. In this mode the outputs are directly driven by the SYNC input (per the block diagram). This mode can
also be used for low frequency board testing.
Note: If the outputs are put into 3–state during normal PLL operation, the loop will be broken and phase–lock will be lost. It will
take a maximum of 10mS (tLOCK spec) to regain phase–lock after the OE/RST pin goes back high.
