IN3_CMOS: Input Clock 3
A 2 kHz, 4 kHz, N x 8 kHz
25.92 MHz, 38.88 MHz, 51.84 MHz, 77.76 MHz or 155.52 MHz clock is input on this pin.
FRSYNC_8K: 8 kHz Frame Sync Output
An 8 kHz signal is output on this pin.
MFRSYNC_2K: 2 kHz Multiframe Sync Output
A 2 kHz signal is output on this pin.
OUT1_POS / OUT1_NEG: Positive / Negative Output Clock 1
A 1 Hz, 400 Hz, 2 kHz, 8 kHz, 64 kHz, N x E1
5 MHz, 10 MHz, 20 MHz, E3, T3, 6.48 MHz, 19.44 MHz, 25.92 MHz, 38.88 MHz, 51.84 MHz,
77.76 MHz, 155.52 MHz, 311.04 MHz or 622.08 MHz clock is differentially output on this pair
of pins.
OUT2: Output Clock 2
A 1 Hz, 400 Hz, 2 kHz, 8 kHz, 64 kHz, N x E1
5 MHz, 10 MHz, 20 MHz, E3, T3, 6.48 MHz, 19.44 MHz, 25.92 MHz, 38.88 MHz, 51.84 MHz,
77.76 MHz or 155.52 MHz clock is output on this pin.
CS: Chip Selection
A transition from high to low must occur on this pin for each read or write operation and this
pin should remain low until the operation is over.
INT_REQ: Interrupt Request
This pin is used as an interrupt request. The output characteristics are determined by the
HZ_EN bit (b1, 0CH) and the INT_POL bit (b0, 0CH).
SDI: Serial Data Input
In Serial mode, this pin is used as the serial data input. Address and data on this pin are seri-
ally clocked into the device on the rising edge of SCLK.
CLKE: SCLK Active Edge Selection
In Serial mode, this pin selects the active edge of SCLK to update the SDO:
High - The falling edge;
Low - The rising edge.
SDO: Serial Data Output
In Serial mode, this pin is used as the serial data output. Data on this pin is serially clocked
out of the device on the active edge of SCLK.
SCLK: Shift Clock
In Serial mode, a shift clock is input on this pin.
Data on SDI is sampled by the device on the rising edge of SCLK. Data on SDO is updated
on the active edge of SCLK. The active edge is determined by the CLKE.
TRST: JTAG Test Reset (Active Low)
A low signal on this pin resets the JTAG test port.
This pin should be connected to ground when JTAG is not used.
TMS: JTAG Test Mode Select
The signal on this pin controls the JTAG test performance and is sampled on the rising edge
of TCK.
