ATA6841N-PLSW Datasheet

SYMBOL PIN NUMBER TYPE DESCRIPTION
CLOCK AND RESET SIGNALS
CLR# 32 l reset signal, active low
XIN 8 l Crystal oscillator input pin. When USE_NCO pin is high a third overtone XTAL should be connected between the XIN and XOUT pins. When USE_NCO pin is low a VCXO should be connected between XIN and via a RC filter to the CTRL_VCXO output.
XOUT 9 O Crystal oscillator output pin.
SACLK 25 O (5V) Sampling frequency output. This output clock can be fed to an external (10-bit) ADC as sampling clock. SACLK= XIN/2
USE NCO 33 l When low the chip is in VCXO mode else in NCO mode
CTRL VCXO 26 O (5V) If not in NCO mode, control of an external sampling VCXO (after low- pass filtering)
CLK X1 1 81 O (5V) Internal SACLK equivalent monitoring output.
CLK X2 1 80 O (5V) Internal SACLK* 2 equivalent monitoring output.

The integrator capacitor CINT (see Figure l) affects the magnitude of the integrator voltage waveform. Its absolute accuracy is not critical since it does not affect the transfer function. This allows a wide range of capacitance to produce excellent results. Figure 4 facilitates choosing an appropriate

respectively, and FO~ is used only for the watchdog timer operation. When this bit is a ONE, the Protocol Controller is in the Internal Timing Mode. The transmit and receive sections are enabled by the internally generated timings derived from the inputs CKi and FOi. The FOi input defines the beginning of a frame (Figure 24) and the transmitter and receiver sections are enabled in the timeslots as determined
