CY24204ZXC-3T

Clock Generators, PLLs, Frequency Synthesizers Overview

The CY24204ZXC-3T is a MediaClock DTV and STB clock generator manufactured by Cypress Semiconductor. It integrates a phase-locked loop (PLL) to generate low-jitter, high-accuracy outputs from a 27-MHz crystal input. The device provides four outputs: two copies of a 27-MHz reference clock and two selectable output clocks operating at 27 MHz, 27.027 MHz, 74.250 MHz, or 74.17582418 MHz. It operates on a single 3.3V supply with an ambient temperature range of 0°C to 70°C. The component features an analog VCXO control for frequency tuning and is housed in a 16-pin TSSOP package.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix 'ZXC' corresponds to the 16-pin TSSOP package and commercial temperature grade as listed in the ordering information. Confirm that the '-3' variant matches the standard ±150 ppm VCXO pull range rather than the extended range found in other variants. Ensure compliance with the manufacturer's note stating this product family is not recommended for new designs.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select the CY24204ZXC-3T when a 27-MHz crystal input is available and multiple clock frequencies are required from a single source. Compare against the -4 variant if an extended VCXO pull range of ±200 ppm is necessary. Verify load capacitance requirements do not exceed 15 pF per output. Check that the 3.3V supply voltage aligns with the system power rails.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the MediaClock series designed for digital video applications. It serves as a replacement for traditional discrete oscillators and synthesizers. The part number indicates the -3 functional variant packaged in tape and reel format. Other variants in the series include -4 and -5, which offer different pull ranges and drive strengths respectively.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Public confirmed substitute part numbers are not provided in the datasheet. Designers should consult the manufacturer for current alternatives as the document notes the product is not recommended for new designs.
