CY7B991-5JXCT - Brand New Cypress Semiconductor IC Chips
-
Description
The CY7B991-5JXCT is a programmable skew clock buffer that offers user-selectable control over system clock functions. It is designed to optimize the timing of high-performance computer systems. With eight individual drivers arranged in four pairs of user-controllable outputs, this clock buffer can drive terminated transmission lines with impedances as low as 50Ω. It provides minimal and specified output skews and delivers full swing logic levels (CY7B991 TTL or CY7B992 CMOS).
Specifications and Features
- All output pair skew <100 ps typical (250 ps maximum)
- 3.75 MHz to 80 MHz output operation
- User-selectable output functions:
- Selectable skew to 18 ns
- Inverted and non-inverted
- Operation at 1⁄2 and 1⁄4 input frequency
- Operation at 2x and 4x input frequency (input as low as 3.75 MHz)
- Zero input to output delay
- 50% duty cycle outputs
- Outputs drive 50Ω terminated lines
- Low operating current
- 32-pin PLCC/LCC package
- Jitter <200 ps peak-to-peak (< 25 ps RMS)
Application Scenarios
The CY7B991-5JXCT clock buffer is commonly used in high-performance computer systems where precise timing is required. It can be used in applications such as data centers, networking equipment, telecommunications systems, and industrial automation.
