Detailed Description for CY2305SC-1T
Product Overview
The CY2305SC-1T from Cypress Semiconductor Corp is a surface-mount zero delay buffer for clock distribution in 3 V to 3.6 V timing circuits. The device accepts a non-differential clock input and provides a non-differential clock output with a 1:5 input-to-output ratio, with a maximum frequency of 133.33 MHz. The PLL can be bypassed, allowing use in configurations that require PLL operation or direct clock transfer. The 8-SOIC package supports surface-mount assembly and operates over a temperature range of 0°C to 70°C.
Key Features
- Zero delay buffer with clock input and clock output.
- 1:5 input-to-output ratio.
- Maximum frequency of 133.33 MHz.
- PLL with bypass.
- Non-differential input and non-differential output.
- Supply voltage range of 3 V to 3.6 V.
- Operating temperature range of 0°C to 70°C (TA).
- One circuit in an 8-SOIC surface-mount package.
Applications
- Buffering a system reference clock before distribution to downstream logic in a 3 V to 3.6 V circuit.
- Maintaining clock alignment in timing-sensitive digital circuits where a zero delay buffer topology is required.
- Distributing a clock signal to multiple load points using the 1:5 input-to-output ratio.
- Providing a bypassable PLL option in circuits that can use either PLL operation or direct clock pass-through.
Design & Procurement Notes
When selecting the CY2305SC-1T, confirm that the board power rail remains within 3 V to 3.6 V and that the clock frequency does not exceed 133.33 MHz. Because the input and output are non-differential, use single-ended clock signals rather than differential pairs. The 8-SOIC surface-mount package requires pad and land-pattern planning for a 3.90 mm wide body. The operating temperature range of 0°C to 70°C should be checked against the enclosure or board thermal environment. The PLL bypass feature gives a choice between PLL operation and bypass operation, so the selected mode must match the timing budget and load arrangement.
