4 / 14 page 4 SP5730 Preliminary Information Electrical Characteristics (continued) Tamb= -40 o C to 85 o C, Vcc= 4.5 to 5.5V These characteristics are guaranteed by either production test or design. They apply within the specified ambient temperature and supply voltage unless otherwise stated. Characteristic Pin Value Units Conditions Min Typ Max Buffered REF/COMP output 11 AC coupled 0.5-20MHz output amplitude 0.35 Vpp Enabled by bit RE= 1 output impedance 250 Ω See note 2 Phase detector Comparison 4 MHz frequency Equivalent phase noise at phase dBc/Hz SSB, within loop bandwidth detector -152 Fcomp = 2MHz -158 Fcomp = 125kHz RF division ratio 56 32767 Reference division ratio See Table 1 Output ports P0 - P3 6-9 See Note 1 sink current 2 mA Vport = 0.7 Leakage current 10 µA Vport = Vcc Address Select 10 See Figure 4 Table 3 Input high current 1 mA Vin = Vcc Input low current -0.5 mA Vin = Vee Logic level select 6 See note 3 Input high level 3 Vcc V 5V I2C logic selected, or open circuit Input low level 0 1.5 V 3V3 I2C logic selected Input current -10 10 µA Vin = Vee to Vcc Notes: 1. Output ports high impedance on power up, with data, clock, and enable at logic ‘0’ 2. If the REF/COMP output is not used, the output should be left open circuit or connected to Vcc, and disabled by setting RE = 0 3. Bi-directional port. When used as an output, the input logic state is ignored. When used as an input the port should be switched in to high impedance (off) state. |
