3uhvfdohu&lufxlw*+] 30%7 preliminary data bipolar ic 3'62 vignette semiconductor group 3 7.96 )xqfwlrqdo'hvfulswlrq$ssolfdwlrq the ic is designed for use in mobile radio communication devices up to 2100 mhz and upconversion systems up 2500 mhz. due to its low power consumption and low phase noise generation it is suitable for the use in battery powered handheld systems, e.g. pcn, dectand wireless lans. low supply voltage down to 2.7v. it can be switched to a low-power standby mode. internal current source at the emitter follower output. no external resistor needed in typical applications. the divide ratio is 1:64/65 or 1:128/129 depending on the external circuit configuration.
30%7 semiconductor group 4 7.96 &lufxlw'hvfulswlrq the differential inputs of the ic may be connected either balanced or single ended. in the latter case the unused input must be rf-grounded with a capacitor (about 10 pf) with a low serial inductance. depending on the logic level at sw input the basic divide ratio of the ecl-stages is fixed to 1:64/65 or 1:128/129. the mod input determines whether modulus 1:n or 1:n+1 (n=64 or 128 according to sw-level) is active. the ic can be switched to a low-power standby mode (input stb). the mod input is ttl/cmos compatible. the emitter follower output is cmos compatible according to the application circuit on page 11. the minimum logic swing is 0.8 v pp . )xqfwlrqwdeoh ,qsxwslq /rjlfohyho 3uhvfdohuixqfwlrq 6: high = u s -0.1 v to u s low = gnd to 0.8 v or open 1:64/65 1:128/129 02' high = 2.0 v to u s or open low = gnd to 0.8 v 1:64/1:128 1:65/1:129 67% high = u s -0.1 v to u s low = gnd to 0.8 v divider q=high, standby-mode
