It uses a hybrid analog-digital PLL architecture combining a delta-sigma fractional-N frequency synthesizer with a digital PLL to generate precise output clock frequencies. The device supports both I2C and SPI control interfaces and features CLK_IN skipping mode for applications with intermittent or missing reference clocks.","working_principle":"The CS2300CP combines an analog delta-sigma fractional-N frequency synthesizer with a digital PLL. The internal LCO provides a stable low-jitter reference clock. The fractional-N synthesizer multiplies this reference by a programmable factor N to generate the output frequency. The digital PLL compares the ratio of output and reference clocks, calculates the optimal N value, and automatically adjusts the loop filter bandwidth. The I2C interface allows bidirectional register access, while the SPI interface supports write-only operation at speeds up to 6MHz. CLK_IN skipping mode enables operation when the reference clock is intermittent.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Type<\/th><th>Function<\/th><\/tr><tr><td>1<\/td><td>FILTP<\/td><td>Analog<\/td><td>LCO filter capacitor (+)<\/td><\/tr><tr><td>2<\/td><td>FILTN<\/td><td>Analog<\/td><td>LCO filter capacitor (-)<\/td><\/tr><tr><td>3<\/td><td>CLK_IN<\/td><td>Input<\/td><td>Reference clock input<\/td><\/tr><tr><td>4<\/td><td>VDD<\/td><td>Power<\/td><td>Supply voltage (3.3V)<\/td><\/tr><tr><td>5<\/td><td>GND<\/td><td>Power<\/td><td>Ground<\/td><\/tr><tr><td>6<\/td><td>CLK_OUT2<\/td><td>Output<\/td><td>Clock output 2<\/td><\/tr><tr><td>7<\/td><td>CLK_OUT1<\/td><td>Output<\/td><td>Clock output 1<\/td><\/tr><tr><td>8<\/td><td>SCL\/CCLK<\/td><td>Input<\/td><td>I2C clock \/ SPI clock<\/td><\/tr><tr><td>9<\/td><td>SDA\/CDIN<\/td><td>I\/O<\/td><td>I2C data \/ SPI data in<\/td><\/tr><tr><td>10<\/td><td>CS\/AD0<\/td><td>Input<\/td><td>SPI chip select \/ I2C address<\/td><\/tr><\/table>","application_scenarios":"<ul><li>Precision audio clock generation for DACs and ADCs<\/li><li>Video timing reference clock synthesis<\/li><li>Telecom networking clock jitter cleaning<\/li><li>Consumer electronics clock distribution<\/li><li>Mixed-signal board clock management<\/li><\/ul>","alternative_models":"<table><tr><th>Manufacturer<\/th><th>Part Number<\/th><th>Package<\/th><th>Notes<\/th><\/tr><tr><td>Cirrus Logic<\/td><td>CS2300CP-CZZ<\/td><td>10-MSOP<\/td><td>Tube version<\/td><\/tr><tr><td>Cirrus Logic<\/td><td>CS2000-CP<\/td><td>10-MSOP<\/td><td>Similar fractional-N synthesizer<\/td><\/tr><tr><td>TI<\/td><td>LMK61E2-SI<\/td><td>QFN-24<\/td><td>Programmable clock generator<\/td><\/tr><tr><td>Silicon Labs<\/td><td>SI5351A-B-GT<\/td><td>QFN-20<\/td><td>I2C programmable clock, 3 outputs<\/td><\/tr><tr><td>Microchip<\/td><td>MCP7940N-I\/SN<\/td><td>8-SOIC<\/td><td>I2C RTC with clock output<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts\/2800","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/comments?post=2800"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts\/2800\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/media\/2817"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/media?parent=2800"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/categories?post=2800"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/tags?post=2800"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/chip_brand?post=2800"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
