| SY10/100EP451L 3.3V ECL 6-Bit Differential Register with Master Reset General Description The SY10/100EP451L is a 6-bit fully differential register with common clock and single-ended Master Reset (MR). It is ideal for very high frequency applications where a registered data path is necessary. All inputs have an internal 75k pull-down resistor. Differential inputs have an override clamp. Unused differential register inputs can be left open and will default LOW. When the differential inputs are forced to < VEE +1.2V, the clamp will override and force the output to a default state. The positive transition of CLK (pin 4) will latch the registers. Master Reset (MR) HIGH will asynchronously reset all registers forcing Q outputs to go LOW. Datasheets and support documentation can be found on Micrel's web site at: www.micrel.com.

If input pin is left open, it will default to LOW. ECL Differential Clock Input: This input pair is the clock signal input to the device. Each input pin is connected to a 75k pull-down resistor. Due to an internal clamping circuit, CLK will default LOW and /CLK will default HIGH if left open. ECL Differential Data Inputs: These input pairs are the different data signal inputs to the device. Each input pin is connected to a 75k pull-down resistor. Due to an internal clamping circuit, D will default LOW and /D will default HIGH if left open.

SY10/100EP451L LVPECL Output Interface Applications LVPECL output has very low output impedance (open emitter), and small signal swing which results in low EMI. LVPECL is ideal for driving 50 and 100 controlled impedance transmission lines. There are several techniques in terminating the LVPECL output, as shown in Figures 2 through 4. Figure 4. Terminating Unused I/O Notes: 1. 2. Unused output (/Q) must be terminated to balance the output. Unused output pairs (Q and /Q) may be left floating. Figure 2. Parallel Termination-Thevenin Equivalent Figure 3. Three-Resistor "Y-Termination" Notes: 1. 2. 3. 4. Power-saving alternative to Thevenin termination. Place termination resistors as close to destination inputs as possible. Rb resistor sets the DC bias voltage, equal to VCC-2V. C1 is an optional bypass capacitor intended to compensate for any tr, tf mismatches. March 2007 9 M9999-030507-A hbwhelp@micrel.com or (408) 955-1690 Micrel, Inc.
