1 / 14 page SM5073 series SEIKO NPC CORPORATION —1 VCXO ICs with Built-in Varicap OVERVIEW The SM5073 series are VCXO ICs with built-in varicap diode. They use a recently developed negative-resis- tance switching oscillation circuit, at oscillation startup and during normal oscillation, for both good oscilla- tion startup characteristics and wide pullrange. Furthermore, it employs a CMOS process varicap diode, and also features all the necessary VCXO structure circuit components on a single chip, forming a VCXO with just the connection of an external crystal. FEATURES I 3.0 to 3.6V supply voltage range I 10MHz to 60MHz operating frequency (varies with version) I Uses negative-resistance switching function I Varicap diode built-in I Frequency divider built-in (varies with version: fO, fO/2, fO/4, fO/8, fO/16, fO/32) I CMOS output level I 50 ± 10% output duty I 6mA (min) output drive capability I 15pF output load capacitance CL I Standby function High impedance in standby mode (oscillator continues running) I Package: 8-pin SOP (SM5073 ××S) APPLICATIONS I VCXO modules I Communications application I Networking application I Broadcasting application PACKAGE DIMENSIONS (Unit: mm) SERIES LINEUP ORDERING INFORMATION 5.2 0.3 0.4 0.1 0.15 + 0.1 − 0.05 0 to 10 0.695typ 1.27 0.12 M 0.10 Version Typical oscillation frequency1 [MHz] 1. The typical oscillation frequency is the oscillation frequency criteria for use when selecting the device version. Note that the oscillation characteristics and pullability vary with the crystal used and the mounting conditions. Even for the same frequency, the optimal version can vary with crystal characteristics, so careful evaluation should be exercised when selecting the device version. Output frequency SM5073 ×1S SM5073 ×2S2 2. These versions are produced after receiving a purchase order. Please ask our Sales & Marketing section for further detail.
