SP8402KG 数据手册
SP8402 Very Low Phase Noise Divider by 2N September 2005 The SP8402 is a very low phase noise divider which divides by powers of two. The S0, S1, S2 data inputs select the division ratio in the range 21 to 28. Special circuits techniques have been used to reduce the phase noise considerably below that produced by standard dividers. The data inputs are CMOS or TTL compatible. The SP8402 is packaged in a 28 pin plastic SO package to be compatible with the SP8400 and SP8401 devices.
