CYI9531OXCT Overview
As a clock IC, it uses the Tape & Reel (TR) package. 28-SSOP (0.209, 5.30mm Width) contains this Clock PLL. When reflowed, this frequency generator can withstand a maximum temperature of NOT SPECIFIED. As a result, frequency synthesizers can be found to contain 28 terminations. For this clock generator ic, a voltage of 3.3V is required. This Clock PLL will be fed by Crystal as its input. There are 1 circuits implemented in order to achieve full performance from this electronic part. Providing a maximum frequency of 133.3MHz, this clock-based RF synthesizer is suitable for a variety of applications. The Surface Mount allows this electrical component to be easily installed on the panel. This RF synthesizer has CLOCK GENERATOR, PROCESSOR SPECIFIC uPs, uCs, and peripheral ICs. There are 3.135V~3.465V different supply voltages that can be provided for this RF synthesizer. Based on test statistics, ambient temperature should be set at 0°C~70°C. I would like to present to you a frequency synthesizer that is compatible with LVCMOS logic levels. In particular, this clock PLL is designed to be used with microprocessors. CYI9531 is the base part number for finding related electronic parts. 6 signal outputs allow for maximi6ation of output frequency.
