Due to low power consumption and low phase noise generation, the PMB2314T is suitable for use in battery powered handheld systems, e.g. GSM, cordless telephones and cordless consumer products, as well as in basestations. 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. 1.2 Circuit Description 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 12. The minimum logic swing is 0.8 Vpp. Table 1 Function Table Input pin Logic level Prescaler function SW HIGH = US-0.1 V to US LOW = GND to 0.8 V or open 1:64/65 1:128/129 MOD HIGH = 2.0 V to US or open LOW = GND to 0.8 V 1:64/1:128 1:65/1:129 STB HIGH = US-0.1 V to US LOW = GND to 0.8 V Divider Q=HIGH, STANDBY-mode Data Sheet 5 Version 1.2, 2003-12-04 PMB 2314T Version 1.5 Pin Assignment 2 Pin Assignment Pin 1 Pin 2 Pin 3 Pin 4 Pin 5 Pin 6 Pin 7 Pin 8 Data Sheet I1 1 8 I2 US 2 7 STB SW 3 6 MOD Q 4 5 GND RF-input I1 supply voltage US divide ratio 1:64/65 - 1:128/129 control input (SW) output Q GND modulus 1:n/n+1 (n=64 or 128) control input (MOD) standby mode control input (STB) RF-input I2 6 Version 1.2, 2003-12-04 PMB 2314T Version 1.5 Block Diagram 3 Block Diagram US STB I2 2 7 Uref 4 8 Q 1:64/65 1:128/129 I1 SW 1 I 3 6 MOD 5 GND Data Sheet 7 Version 1.2, 2003-12-04 PMB 2314T Version 1.5 Absolute Maximum Ratings 4 Absolute Maximum Ratings TA = -40 to 85 °C Parameter Supply voltage Input level (Pin 1; Pin 8) Voltage swing (Pin 1 to 8) Input level (Pin 3; Pin 6; Pin 7) Symbol US UI Limit Values min. max. -0.3 6 2 Unit V V UI18 -2 2 V USW, UMOD, USTB, -0.3 US+0.7V or 5.5V if US+0.7V > 5.5V US V Remarks US=0V US=2.7...5.5V V Output level UQ (Pin 4) 5 mA Output current -IQ (Pin 4) 125 °C Junction temperature Tj -65 125 °C Storage temperature TS Thermal resistance Rthsa 185 K/W system-ambient The maximum ratings may not be exceeded under any circumstances, not even momentarily and individually, as permanent damage to the IC will result.
