| Micrel, Inc. 3.3V 800MHz PRECISION PECL AMPLIFIER WITH LOW-GAIN FEEDBACK Precision Edge SY89207L Precision Edge(R) SY89207L (R) s 3.0V to 3.8V power supply option s Guaranteed AC parameters over temperature: * fMAX = 800MHz * < 200ps differential propagation delay (D to QFB) * < 730ps differential propagation delay (D to QHG) * < 250ps tr / tf s Low-gain feedback path QFB = +10V/V s VBB reference output voltage s Wide temperature range: -40C to +85C s Available in 10-pin (3mm x 3mm) MSOP s LVPECL/LVECL/CMOS compatible EN option Precision Edge(R) DESCRIPTION The SY89207L is a differential receiver amplifier optimized for crystal oscillator applications. The device includes an additional low differential gain (+10V/V) output stage (QFB) ideal for feedback applications common in crystal oscillator gain blocks. The SY89207L is fully differential, with a bandwidth > 800MHz over temperature and voltage. For applications that require output disable control, a LVPECL/LVECL/CMOS compatible enable pin (EN) will force the differential output into a fixed logic state. The SY89207L also includes a VBB reference voltage for single-ended or AC-coupled applications. The SY89207L PECL logic is 100k ECL compatible. Operation is guaranteed over the -40C to +85C temperature range and 3.3V nominal supply voltage range. All support documentation can be found on Micrel's web site at www.micrel.com.

PIN DESCRIPTION Pin Number 1, 2 3, 4 5 Pin Name QFB, /QFB D, /D VBB Pin Function Differential clock outputs for feedback path: Nominal DC gain +10. LVPECL, LVECL differential inputs: Internal 75k pull-down resistor. VCC -1.32V reference voltage for single-ended inputs: It provides the switching reference for the input differential amplifier. When unused, it can be left open. For single-ended PECL applications connect VBB to /D input. For differential AC-coupled inputs, terminate each input with 50 to VBB as close to the input pins as possible. Always bypass the VBB pin with a 0.01F capacitor to VCC. Enable: LVPECL/LVECL/CMOS compatible input control with internal 25k pull-up resistor. It enables/disables the high-gain output (QHG). Default state is enabled, logic HIGH, if left floating When EN pin is pulled to a logic LOW or GND, the QHG output pair will be latched, as described in the "Truth Table." EN is synchronous so that the outputs will only be enabled/disabled when they are in the LOW state. Input threshold is VBB. Negative power supply: For LVECL operation, connect to negative supply. For LVPECL operation, connect to GND. Differential high-gain outputs: Nominal DC gain is greater than +200. Positive power supply: For LVECL operation, connect to VCC = 0V. For LVPECL operation, connect to 3.3V. Bypass with 0.1F0.01F low ESR capacitors. 6 EN 7 8, 9 10 VEE QHG, /QHG VCC TRUTH TABLE EN 1 0 QHG Out Data Logic Low /QHG Out /Data Logic High M9999-051805 hbwhelp@micrel.com or (408) 955-1690 2 Micrel, Inc.
