Part Name(s) : HC49-4H HC49-4HL
Description : Low-cost, industry-standard crystal unit
HC49-4H crystals share the same base outline as the industry standard HC49 crystal. The crystal uses at AT-cut strip crystal with an hermetically sealed can. HC49-4H crystals provide a low cost source of system clock frequency.
• Low-cost, industry-standard crystal unit
• AT-Cut strip crystal with hermetically sealed can
The MC12061 is for use with an external crystal to form a crystal controlled oscillator. In addition to the fundamental series mode crystal, two bypass capacitors are required (plus usual power supply pin bypass capacitors). Translators are provided internally for MECL and TTL outputs.
• Frequency Range = 2.0 to 20 MHz • Temperature Range = 0 to + 70°C • Single Supply Operation: +5.0 Vdc or –5.2 Vdc • Three Outputs Available: 1. Complementary Sine Wave (600 mVpp typ) 2. Complementary MECL 3. Single Ended TTL
