What should engineers review before using CDCS503TPWRQ1?

Verify the selected FS mode: x1 accepts 8 MHz to 32 MHz input, while x4 accepts 8 MHz to 27 MHz input. Check the resulting 8 MHz to 108 MHz output range, SSC tolerance, 15 pF output-load test condition, and the OE high-impedance output behavior.

What is the pinout of CDCS503TPWRQ1?

Use the CDCS503TPWRQ1 datasheet for the official pinout diagram and pin names. In PartGenie, ask Datasheet AI about CDCS503TPWRQ1 pinout to locate pins, power rails, and interface signals before layout.

AI summary

CDCS503TPWRQ1 is a 3.3 V automotive LVCMOS clock buffer and PLL multiplier that provides x1 or x4 clock output with selectable center-spread clocking for EMI reduction.

Best for

Automotive LVCMOS clock buffering
Clock multiplication from an 8 MHz to 27 MHz source
EMI reduction using center-spread clocking

Avoid if

A fixed-frequency clock without modulation is mandatory
The required input frequency exceeds the selected FS-mode limit
The design requires a supply outside 3.0 V to 3.6 V

Check before use

FS pin configuration for x1 or x4 output
SSC_SEL0 and SSC_SEL1 spread setting
Clock receiver tolerance to spread-spectrum modulation
Output loading and PCB transmission-line termination

Key specifications

Supply voltage: 3 V to 3.6 V
Output frequency: 8 MHz to 108 MHz
