The AT-cut provides excellent frequency stability over temperature. When placed in the feedback path of an oscillator circuit with appropriate load capacitance, the piezoelectric effect sustains precise oscillation. The 27MHz frequency is commonly used as a reference for video systems (NTSC\/PAL color subcarrier) and RF transceivers.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Function<\/th><\/tr><tr><td>1<\/td><td>Crystal<\/td><td>One terminal of quartz resonator<\/td><\/tr><tr><td>2<\/td><td>Crystal<\/td><td>Other terminal of quartz resonator<\/td><\/tr><\/table>","application_scenarios":"<ul><li>Video system clock generation<\/li><li>RF transceiver reference<\/li><li>WiFi module reference clock<\/li><li>Industrial timing applications<\/li><\/ul>","alternative_models":"<table><tr><th>Model<\/th><th>Manufacturer<\/th><th>Key Spec<\/th><th>Package<\/th><\/tr><tr><td>ABM8-27.000MHZ-20-B2X-T<\/td><td>Abracon<\/td><td>27MHz 3225<\/td><td>3.2x2.5mm<\/td><\/tr><tr><td>ECS-270-20-3X-TR<\/td><td>ECS<\/td><td>27MHz HC49S<\/td><td>11.4x4.8mm<\/td><\/tr><tr><td>FX135A-270 27MHz<\/td><td>Ikeji<\/td><td>27MHz HC49S<\/td><td>11.4x4.8mm<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/posts\/9838","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/comments?post=9838"}],"version-history":[{"count":0,"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/posts\/9838\/revisions"}],"wp:attachment":[{"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/media?parent=9838"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/categories?post=9838"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/tags?post=9838"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/chip_brand?post=9838"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
