HARDWARE AND STATUS PINS
Receive Voice Synchronization Input. Receive sync that indicates
frame boundaries present on RVDATA – referenced to RVCLK, frequency
of 8 kHz. This signal is only available on the DS33W41 and DS33W11.
Receive Voice Data Enable: May be used in place of a gapped RVCLK.
If low, RVDATA is valid. If gapped RVCLK is used and this signal is not
used, tie this input low. This signal is only available on the DS33W41 and
DS33W11.
High-Impedance Test Enable (Active Low). This signal puts all digital
output and bi-directional pins in the high impedance state when it is low
and JTRST is low. For normal operation tie high. This is an asynchronous
input.
Reset (Active Low). An active low signal on this pin resets the internal
registers and logic. While this pin is held low, the microprocessor interface
is kept in a high-impedance state. This pin should remain low until power
is stable and then set high for normal operation.
System Clock In: 125MHz, ±100ppm System Clock input.
JTAG Reset (Active Low). JTRST is used to asynchronously reset the
test access port controller. After power-up, a rising edge on JTRST will
reset the test port and cause the device I/O to enter the JTAG DEVICE ID
mode. Pulling JTRST low restores normal device operation. JTRST is
pulled HIGH internally via a 10kΩ resistor operation. If boundary scan is
not used, this pin should be held low.
JTAG Clock. This signal is used to shift data into JTDI on the rising edge
and out of JTDO on the falling edge.
JTAG Data Out. Test instructions and data are clocked out of this pin on
the falling edge of JTCLK. If not used, this pin should be left unconnected.
JTAG Data In. Test instructions and data are clocked into this pin on the
rising edge of JTCLK. This pin has a 10kΩ pullup resistor.
JTAG Mode Select. This pin is sampled on the rising edge of JTCLK and
is used to place the test access port into the various defined IEEE 1149.1
states. This pin has a 10kΩ pullup resistor.
