SY75576L
267MHz 1:4 3.3V HCSL/LVDS Fanout Buffer
PrecisionEdge™
General Description
The SY75576L is a high-speed, fully differential 1:4 clock
fanout buffer optimized to provide four identical output
copies with 137fs phase jitter and maximum 50ps output-
to-output skew. Designed to be used with PCI-Express
applications, SY75576L accepts and outputs HCSL or
LVDS logic levels.
The SY75576L operates from a 3.3V ±5% power supply
and is guaranteed over the full industrial temperature
range (−40°C to +85°C). It is available in a 20-pin TSSOP
lead-free package.
The SY75576L is part of Micrel’s high-speed, ultra-low
jitter, PrecisionEdge™ product line.
Datasheets and support documentation are available on
Micrel’s web site at: www.micrel.com.

Pin Function
SEL = 0 propagates IN2, /IN2 to outputs. SEL = 1 propagates IN1, /IN1 to outputs. Internal pull-
up resistor, IN1, /IN1 is selected by default.
3.3V power supply
HCSL/LVDS input 1
HCSL/LVDS inverted input 1
PD = 0 powers down the chip and tri-states outputs. The pin is attached to an internal pull-up
resistor.
HCSL/LVDS input 2
HCSL/LVDS inverted input 2
Tri-state outputs. High = enable outputs. Low = disable outputs. Internal pull-up resistor, outputs
are enabled by default.
