The SY100EP210U is a high-speed, precision low skew

1-to-5 dual differential clock driver. HSTL inputs can be

used when the EP210U is operating in PECL mode.

The EP210U specifically guarantees critical AC

parameters over temperature and voltage. Optimal design,

layout, and processing minimize skew within device and

from device-to-device.

The SY100EP210U, as with most other ECL devices,

can be operated from a positive VCC supply in PECL mode.

This allows the EP210U to be used for high performance

clock distribution in +3.3V or +2.5V systems. Single-ended

input operation is limited to a VCC ≥3.0V in PECL mode, or

VEE ≤–3.0V in ECL mode.

Designers can take advantage of the EP210U’s

performance to distribute low skew clocks across the

backplane or to multiple points on a board.

Pin Function

CLKa, /CLKa LVPECL, LVECL, HSTL Clock Input: CLKa input includes a 75kΩ pull-down. Default is LOW if left floating.

/CLKa includes both pull-up and pull-down resistors. Default condition is VCC/2.

CLKb, /CLKb LVPECL, LVECL, HSTL Clock Input: CLKb input includes a 75kΩ pull-down. Default is LOW if left floating.

/CLKb includes both pull-up and pull-down resistors. Default condition is VCC/2.

Qn0:4, /Qn0:4 LVPECL or LVECL Outputs: Terminate to VCC–2V. (see “Termination” section)

VBB Reference Voltage for Single-Ended Inputs: It provides the switching reference for the input differential amplifier.

When used, bypass with a 0.0µF capacitor to the most positive reference (usually VCC) as shown in Figure 3.

VCC Positive Power Supply: For LVPECL operation, connect VCC to 3.3V or 2.5V. For LVECL operation, connect to

GND. Bypass with 0.1µF//0.01µF low ESR capacitors.

VEE Negative Power Supply: For LVPECL operation, connect to GND. For LVECL operation, connect to –3.3V or

–2.5V.
