843071I数据手册Renesas中文资料规格书

描述 Description

The 843071I is a Serial ATA (SATA)/Serial Attached SCSI (SAS) Clock Generator. The 843071I uses an 18pF parallel resonant crystal over the range of 20.833MHz - 28.3MHz. For SATA/SAS applications, a 25MHz crystal is used and either 75MHz or 150MHz may be selected with the FREQ_SEL pin. For 10Gb Fibre Channel applications, a 26.5625MHz crystal is used for 159.375MHz output. The 843071I has excellent <1ps phase jitter performance, over the 12kHz - 20MHz integration range. The 843071I is packaged in a small 8-pin TSSOP, making it ideal for use in systems with limited board space.
