PL685-28
PL685-28 is 19MHz to 250MHz Low Phase-Noise XO manufactured by Micrel Semiconductor.
(Preliminary) PL685-28 FE AT UR E S 19MHz to 250MHz Low Phase-Noise XO PAD CONFIGURATION - < 0.6ps RMS phase jitter (12k Hz to 20MHz) at 155.52MHz - 30ps max peak to peak period jitter - 8bit Switch Capacitor for ±50PPM crystal CLoad tuning о Load Capacitance Tuning Range: 8p F to 12p F - Ultra Low-Power Consumption о < 90 m A @155MHz PECL output о <10A at Power Down (PDB) Mode - Input Frequency: о Fundamental Crystal: 19MHz to 40MHz - Output Frequency: о 19MHz to 250MHz output. - Output types: LVPECL. - Programmable OE input polarity selection. - Power Supply: 3.3V, ±10% - Operating Temperature Ranges: о mercial: 0C to 70C о Industrial: -40C to 85C - Available in Die or Wafer DESCRIPTION The PL685-28 is a Dual LC core monolithic IC clock, capable of maintaining sub-1ps RMS phase jitter, while covering a wide frequency output range up to 250MHz, without the use of external ponents. The high performance and high frequency output is achieved using a low cost fundamental crystal of between 19MHz and 40 MHz. The PL685-28 is designed to address the demanding requirements of high performance applications such as Fiber Channel, serial ATA, Ethernet, SAN, SONET/SDH, etc. 88.6 mil XIN XOUT 65 mil SCLK 9 Die ID OE/PDB/ SDIO 10 11 GND_ANA GND_DIG GND_BUF 12 13 14 (0,0) PL685 (1650,2250) 6 VDD_ANA 5 VDD_DIG 4...
