Description

The CY2304S1-2 is an electronic component model belonging to Product Category IC chips. It is a low-cost 3.3V zero delay buffer that is designed to distribute high-speed clocks. The device is available in 16-pin SOIC or TSSOP packages. It is an 8-pin version of CY2309, and it accepts one reference input and drives out five low-skew clocks. The -1H version of this device operates at up to 100/133 MHz frequencies and has higher drive than the -1 devices.

Specifications and Features

• Operating Range: 10 MHz to 100/133 MHz
• Compatible with CPU and PCI bus frequencies
• Zero input-output propagation delay
• 60 ps typical cycle-to-cycle jitter (high drive)
• Multiple low-skew outputs with 85 ps typical output-to-output skew
• One input drives five outputs (CY2305)
• One input drives nine outputs grouped as 4 + 4 + 1 (CY2309)
• Compatible with Pentium-based systems
• Test Mode to bypass phase-locked loop (PLL) (CY2309 only [see “Select Input Decoding” on page 3])
• Available in space-saving 16-pin 150-mil SOIC or 4.4-mm TSSOP packages (CY2309), and 8-pin, 150-mil SOIC package (CY2305)
• 3.3V operation
• Industrial temperature available

Application Scenarios

The CY2304S1-2 can be used in devices that require high-speed clock distribution, such as Pentium-based systems, CPUs, and PCI buses.

Comparison

• Low-cost 3.3V zero delay buffer
• Zero input-output propagation delay
• Compatible with Pentium-based systems
• Multiple low-skew outputs
• Available in space-saving SOIC or TSSOP packages
• 3.3V operation

• The device is designed to work with 3.3V, which may not be suitable for all applications.
• The test mode to bypass phase-locked loop (PLL) is only available in CY2309.
