It accepts one or two LVTTL inputs and provides up to 13 LVTTL outputs, with a maximum operating frequency of 200 MHz. The supply voltage range of 2.97V to 3.63V lets it run on a standard 3.3V rail with margin for ripple. The commercial temperature grade (0°C to 70°C) suits office equipment, telecom indoor racks, and test gear — not engine bays or outdoor enclosures. ## 52-TQFP package and layout considerations Housed in a 52-lead TQFP (10x10 mm body), the CY7B9973V-AC is hand-solderable with a fine-tip iron and a steady hand — no hot-air rework required. The pitch is forgiving enough for a two-layer board if the fan-out traces are kept short, though a four-layer stack-up with a solid ground plane under the PLL core improves jitter performance. The input side accepts differential or single-ended LVTTL; the output side is single-ended LVTTL only. The 2:13 ratio means you can feed two independent clock sources and select between them, or use one input and leave the other grounded — the datasheet covers the logic thresholds. ## Active production, RoHS non-compliant The part is RoHS non-compliant (lead-bearing solder balls or die-attach), so it cannot ship into EU RoHS-required assemblies without an exemption. For RoHS-constrained BOMs, check the CY7B9973V-AC's lead-free variant or a pin-compatible alternative.","metaTitle":"CY7B9973V-AC Infineon 200 MHz LVTTL 52-TQFP","metaDescription":"CY7B9973V-AC from Infineon is a PLL-based clock driver, 200 MHz max, 2:13 LVTTL fanout, 52-TQFP.
