l Standard I2C bus format control with built-in read mode
l 3-wire bus 27-bit format control
l 4-bit bandswitch drive transistor
l 5-level A / D converter (when I2C bus selected)
l Frequency step
: 50 kHz, 62.5 kHz, 250 kHz, and
333.3 kHz (at 4 MHz X'tal used)
l Phase lock detector
l Various function settings via program data
l Four address settings via address selector (when I2C bus selected)
l Power on reset circuit
l Flat, compact package
: SSOP16 (0.65 mm pitch)
l Power on reset operation condition
Bandswitch register 1 to 4
: OFF
Tuning amplifier
: ON
Tuning Voltage output (Vt)
: High Level
Charge-pump output current : ±200 µA
Phase comparator reference frequency divider ratio : 1 / 80
