Product Overview
A nine-output 3.3 V clock buffer from Cypress, the CY2309NZSC-1H takes one clock and hands a copy to each of nine outputs, sized for the memory sockets of PC SDRAM boards. It comes in a 16-pin SOIC. Cypress is now part of Infineon, and this number is obsolete at the maker.
Key Features
- Maker part number CY2309NZSC-1H, Cypress (now Infineon)
- Nine outputs, 1:9 fanout
- Outputs up to 133.33 MHz
- Supply 3.0 V to 3.6 V (3.3 V nominal)
- Eight outputs able to drive two DIMMs or four SO-DIMMs
- Commercial temperature range, 0 to +70 C
- 16-pin SOIC, 3.90 mm (0.154 in) body width
Applications
- Board-level repair of SDRAM-era PC motherboards and memory boards built around the CY2309NZSC-1H
- Bench and hobby builds that need one 3.3 V clock copied to several loads
Frequently Asked Questions
Is this the industrial-temperature version?
No. SC is the commercial grade, 0 to +70 C. The industrial version is the CY2309NZSI-1H.
Is this the same chip as a plain CY2309?
No. The CY2309NZ is a separate device from the plain CY2309 and the CY2309C, and the NZ in the part number is what tells them apart.
In the SDRAM years, a chip like the CY2309NZ kept a motherboard's memory sockets marching to one beat. It is easy to overlook on those boards until a memory socket goes quiet, which is when the scope probe belongs on its nine outputs.
