CY7B9973V RoboClock®, High-Speed Multi-Output PLL Clock Buffer | Cypress Semiconductor
CY7B9973V RoboClock®, High-Speed Multi-Output PLL Clock Buffer
This product datasheet is no longer supported by Cypress. We have a new product family called CY7B991, which we recommend in its place. Please click here or contact your local sales representative for more information.
High Speed Multi-Output PLL Clock Buffer
10 MHz to 200 MHz output operation
Output-to-output skews < 350 ps
13 LVTTL 50% duty cycle outputs capable of driving 50Ω terminated lines
Phase-locked loop (PLL) LOCK indicator
3.3V LVTTL/LV differential (LVPECL) hot insertable reference inputs
Multiply/divide ratios of (4, 6, 8, 10, 12, 16, 20) : (2, 4, 6, 8, 10, 12, 16, 20)
Operation with outputs operating at up to 10x input frequency
Low cycle-to-cycle jitter (< ±75 ps peak-peak)
Single 3.3V ± 10% supply
52-pin TQFP package
The CY7B9973V Low Voltage PLL Clock Buffer offers user-selectable frequency control over system clock functions. This twelve output clock driver provides the system integrator with selectable frequency ratios of 1:1, 2:1, 3:1, 3:2, 4:3, 5:1, 5:2, 5:3, 6:1 and 6:5 between outputs. An additional output is dedicated to providing feedback information to allow the internal PLL to multiply an external reference frequency by 4, 6, 8, 10, 12, 16 or 20. The completely integrated PLL reduces jitter and simplifies board layout.
Dear valued customer,
Thank you for choosing our products. They come with all the know-how and passion that our engineers have put into it. As you probably already know, Cypress is now Infineon. This is a major step for our company, but also for the good of you.
Reliability and business continuity are of utmost importance for us. Hence, we remain fully committed to honoring existing customer and distributor relationships. This includes offering the legacy Cypress product portfolio. We thank you very much for your trusting support.
