Infineon CY23EP09ZXI-1H PLL Clock Buffer 16-Pin TSSOP

The -1H version operates up to 220 (200) MHz frequencies at 3.3 V (2.5 V), and has higher drive than the -1 devices. All parts have on-chip PLLs that lock to an input clock on the REF pin. The phase-locked loop (PLL) feedback is on-chip and is obtained from the CLKOUT pad. There are two banks of four outputs each, which can be controlled by the Select inputs. If all output clocks are not required, Bank B can be three-stated. The select inputs also allow the input clock to be directly applied to the outputs for chip and system testing purposes. The PLL enters a power-down mode when there are no rising edges on the REF input (less than ∼2 MHz). In this state, the outputs are three-stated and the PLL is turned off, resulting in less than 25 μA of current draw. In the special case when S2:S1 is 1:0, the PLL is bypassed and REF is output from DC to the maximum allowable frequency. The part behaves like a non-zero delay buffer in this mode, and the outputs are not tri-stated.
