3.3V/5V 800MHz PRECISION PECL AMPLIFIER WITH LOW GAIN FEEDBACK Micrel, Inc. DESCRIPTION FEATURES ■ 3.3V and 5V ±10% power supply options ■ Guaranteed AC parameters over temperature: • fMAX = 800MHz ■ ■ ■ ■ ■ SY100EL16VO SY100EL16VO The SY100EL16VO is a differential receiver amplifier optimized for crystal oscillator applications. The device includes an additional low gain (+10V/V) output stage (QFB) ideal for feedback applications common in crystal oscillator gain blocks. The SY100EL16VO is fully differential, with a bandwidth > 800MHz over temperature and voltage. For applications that require output disable control, an Enable pin (/EN) will force the differential output into a fixed logic state. The SY100EL16VO also includes a VBB reference voltage for single-ended or AC-coupled applications. The SY100EL16VO PECL logic is 100k ECL compatible. Operation is guaranteed over the –40°C to +85°C temperature range and 3.3V to 5V nominal supply voltage range. • < 200ps differential propagation delay (D to QFB) • < 730ps differential propagation delay (D to QHG) • < 250ps tr / tf Low gain feedback path QFB = +10V/V Output enable VBB reference output voltage Wide temperature range: –40°C to +85°C ×3mm) MSOP Available in 10-pin (3× TRUTH TABLE /EN QHG Out /QHG Out 0 Data /Data 1 Logic Low Logic High PIN NAMES BLOCK DIAGRAM Pin QFB VCC /QFB D QHG /D /QHG Differential clock outputs for feedback path: Nominal DC gain +10. D, /D PECL, LVPECL, ECL, LVECL differential inputs: Internal 75kΩ pull-down resistor. VBB 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, and bypass with a 0.01µF capacitor to VCC. /EN Enable: PECL compatible input control with internal 75kΩ pull-down resistor. It controls the high-gain output (QHG). When HIGH, QHG is low and /QHG is high. /EN is synchronous so that the outputs will only be enabled/disabled when they are in the LOW state. VEE Negative power supply: For ECL/LVECL operation, connect to negative supply. For PECL/ LVPECL operation, connect to GND. VBB LEN /EN Q LATCH D Function QFB, /QFB VEE QHG, /QHG Differential high-gain outputs: Nominal DC gain is greater than +200. VCC M9999-121205 [email protected] or (408) 955-1690 Positive power supply: For ECL/LVECL operation, connect to VCC = 0V. For PECL/ LVPECL operation, connect to either 3.3V or 5.0V. Bypass with 0.1µF// 0.01µF low ESR capacitors. Rev.: E 1 Amendment: /0 Issue Date: December 2005 Micrel, Inc.
