The 500 kHz ceiling is the headline constraint — this part is a fit for low-speed timing, micro-controller clock stretching, or fan-out buffering, not for high-frequency PLL synthesis or gigabit serial links. The lack of an internal PLL (PLL: No) means the output frequency is a divided or multiplied version of the input clock, not a synthesized frequency locked to a reference. Supply range spans 3V to 5.5V, so it can run off a 3.3V or 5V rail without an extra regulator — one less line item on the BOM. The 1:1 input-to-output ratio and single circuit count keep the signal path simple: one clock in, one clock out, no channel-to-channel skew to manage. ## Package and footprint: 8-uMAX/uSOP Housed in an 8-TSSOP or 8-MSOP body (0.118\", 3.00mm width), with the supplier device package listed as 8-uMAX/uSOP. Surface-mount only. The 1.1 mm nominal height keeps it usable in tight mezzanine or card-edge layouts. No exposed pad — thermal dissipation goes through the leads, so keep the ambient airflow in mind if the part is near a regulator or other heat source. ## Temperature grade and deployment environment Rated for -40°C to 85°C operating temperature, which covers industrial control cabinets, outdoor telecom enclosures, and automotive cabin environments. Not rated for under-hood or full military range, but the industrial band is the common tier for factory automation, building management, and base-station timing boards. ## Sourcing and lifecycle posture Listed as Active with ROHS3 compliance — no last-time-buy pressure, no discontinuation notice on file. This is a current-production part from Maxim Integrated (now part of Analog Devices), available through the independent distribution channel.","metaTitle":"DS1090U-16+T Clock Generator, 500kHz, 8-uMAX/uSOP","metaDescription":"Maxim Integrated DS1090U-16+T EconOscillator clock generator, 500kHz max, 3V-5.5V, -40°C to 85°C, 8-uMAX.
