CY26121KZXI-21T Overview
Clock generator is packaged in the way of Tape & Reel (TR). Clock PLL is embedded in the 16-TSSOP (0.173, 4.40mm Width) package. The peak reflow temperature (Cel) amounts to 260 to be essentially indestructible. 16 terminations can be found in frequency generators. The supply voltage of 3.3V allows for high efficiency. Clock, Crystal is designed for clock generator's input. 1 circuits are used to achieve clock PLL's superior flexibility. 33.33MHz is the maximal value for normal operation. PLL clock is mounted in the way of Surface Mount. Clock generators should operate with the voltage supply of 3.135V~3.465V. The temperature should be set at -40°C~85°C to ensure reliable performance. Clock is designed for clock generator's output. This electronic component can be classified into Fanout Distribution, Multiplexer, Spread Spectrum Clock Generator. Clock PLL is equipped with 16 pin count. Clock generator is designed with 16 pins. The supply voltage should be maintained at 3.3V for high efficiency. This clock generator is a member of PacketClock™ series. Clock PLL is configured with 5 output. The maximal supply current amounts to 60mA.
