XF Plastic Package Family of Low Phase XF Noise Quartz-based PLL Oscillators Datasheet Description Features Output types: LVDS, LVPECL, CML The XF devices are ultra-low phase noise quartz-based PLL oscillators supporting a large range of frequencies and output Frequency range: 15MHz to 2100MHz interface types. These devices are designed to operate at three Output type: HCSL different power supplies with several pinout configurations, as well Frequency range: 15MHz to 725MHz as two operational temperature ranges. Supply voltage options: 1.8V, 2.5V, or 3.3V The XF devices can be programmed to generate an output Phase jitter (12kHz to 20MHz): 120fs typical frequency from 15MHz to 2100MHz with a resolution as low as Package options: 1Hz accuracy. The configuration capability of this family of devices allows for fast delivery times for both sample and large production 5.0 3.2 mm orders. 3.2 2.5 mm 2.5 2.0 mm Parts are for one time programming (OTP) at the factory for a fixed frequency application, or can be field programmable using Operating temperatures and frequency stability: I2C, based on system needs (see notes under Pin Descriptions). -40C to +85C, 25ppm -40C to +105C, 50ppm Typical Applications FOM Gear Box Data centers 10G / 40G / 100G / 400G Ethernet Pin Assignments Figure 1. 2.5 2.0 mm Package Figure 2. 5.0 3.2 mm and 3.2 2.5 mm Packages SDA 7 NC 1 12 Ground Core 11 NC 2 V Core DD OE 1 6 VDD 3 10 Ground Output Voltage Control 4 9 Output 0b SDA NC 2 5 OUT0b 5 8 Output 0 OE SCL 6 7 V Output DD GND34 OUT0 8 SCL 2021 Renesas Electronics Corporation 1 R31DS0029EU0600 May 10, 2021XF Datasheet Pin Descriptions Table 1.
