Description
DSA557-03/04/05 Multiple Output MEMS PCIe Gen1/2/3/4 Clocks for Automotive Features • Automotive AEC-Q100 Qualified • Complies with PCIe Gen1/2/3/4 Common Clock Spec • Integrated MEMS Resonator Eliminates the Need for External 25 MHz Crystal • Wide Temperature Range: - Automotive Grade 2: –40°C to +105°C - Automotive Grade 3: –40°C to +85°C • 100
More View MHz HCSL/LVDS/LVCMOS Options Available • Dedicated Output Enable (OE) Pins for Clock Outputs • Small Footprints: - 14-Lead VQFN (DSA557-03, Two Outputs) - 20-Lead VQFN (DSA557-04, Three Outputs; DSA557-05, Four Outputs) • Excellent Shock and Vibration Immunity - Qualified to MIL-STD-883 • High Reliability - 20x Better MTF than Quartz Oscillators • Low Current Consumption: 30% Lower than Competing Devices • Supply Range of 2.25V to 3.63V • Lead-Free and RoHS Compliant Applications • Automotive Infotainment • Automotive ADAS • Autonomous Driving • In-Vehicle Network General Description The DSA557 series of high performance PCI Express clock generators use a proven silicon MEMS technology to provide 100 MHz differential output clocks with excellent jitter and stability over a wide range of supply voltages and temperatures. By eliminating the need for quartz or SAW technology, MEMS oscillators significantly enhance reliability and accelerate product development, while meeting stringent clock performance criteria for a variety of communications, storage, and networking applications. The DSA557-03/04/05 have two, three, and four 100 MHz outputs, respectively. All have output enable/disable features. The DSA557-03 is available in a space-saving 14-lead VQFN package. The DSA557-04 and DSA557-05 are available in a 20-lead VQFN. Additional LVDS and LVCMOS output formats are available in addition to the default HCSL output format.  2019 - 2023 Microchip Technology Inc. and its subsidiaries DS20006175D-page 1 DSA557-03/04/05 Package Types DSA557-03 14-Lead VQFN (Top View) DSA557-04 20-Lead VQFN (Top View) DSA557-05 20-Lead VQFN (Top View) NC VDD CLK3+ CLK3CLK2+ CLK2- NC VDD NC NC CLK2+ CLK2- VDD1 VDD0 NC OE NC NC VSS 14 13 12 1 11 2 10 3 9 4 8 567 20 19 18 17 16 15 20 19 18 17 16 15 OE1 1 14 VSS OE1 1 14 VSS CLK0+ NC 2 13 VSS NC 2 13 VSS CLK0- VSS 3 12 NC VSS 3 12 NC CLK1- VSS 4 11 5 6 7 8 9 10 OE2 VSS 4 11 OE2 5 6 7 8 9 10 CLK1+ CLK0CLK0+ CLK1CLK1+ VDD NC CLK0CLK0+ CLK1CLK1+ VDD NC NC NC NC Block Diagrams DSA557-03 Control Circuitry MEMS PLL OE Output Control and Divider DSA557-04 CLK0+ CLK0- CLK1CLK1+ Control Circuitry MEMS OE1 OE2 PLLs Output Control and Divider CLK0+ CLK0- CLK1+ CLK1- CLK2CLK2+ DSA557-05 Note: CLK0+/–, CLK1+/–, CLK2+/–, and CLK3+/– are 100 MHz, per PCIe standards.
